Reparaturplan Fixes: Widget workspace_id check, total bug, context is_visible, permissions, fallbacks

Backend: - Widget total: 0 bug fixed (now returns len(widgets)) - Widget update/delete: now verifies workspace_id + tenant_id (was only tenant_id) - Workspace context: returns all modules with is_visible flag (was only visible modules) - is_workspace_manager() removed (Plan 4.2: no manager checks) - seed_default_workspace: removed hardcoded modules (Plan 4.7: no hardcoded tiles) - Workspace permissions registered in CORE_PERMISSIONS (Plan 2.3) Frontend: - Permission fallback removed: Sidebar/TopBar show nothing while loading (Plan 2.4) - workspaceStore isModuleVisible: fail-closed when isSystemAdmin undefined - WorkspaceManager: AVAILABLE_MODULES replaced with dynamic core+plugin items (Plan 4.4) Tests: - 17 backend tests (removed is_workspace_manager test, adapted widget/context tests) - 13 frontend tests (added undefined-isSystemAdmin test, adapted visibility tests)
Update SANIERUNGS_FORTSCHRITT.md: Phase 6 Workspaces abgeschlossen

 ## Implementierungs-Status (Stand 2026-07-27)
 Die folgenden Phasen wurden gemäß Git-Historie implementiert:
 | Phase | Commit | Maßnahmen | Status |
 |-------|--------|-----------|--------|
 | **Phase 1** (B1-B10) | `5ec1fc9` | Kritische Release-Blocker: Redis-Singleton (B1), Plugin-Routen (B2), UploadFile response_model (B3), DMS-Streaming (B4), Outbox-Worker (B5), Passwort-Reset-Mail (B6), Webhook-SSRF (B7), RLS-DB-Role (B8), .env-Korrektur (B9), Redis-Ports (B10) | ✅ Implementiert |

 ### Verifizierte P0-Behebungen
 | P0 | Problem | Status | Beweis |
 |----|---------|--------|--------|
 | P0-1 | Auth-Bypass via X-Internal-Call | ✅ Behoben | `app/deps.py` hat keinen X-Internal-Call Code mehr. Auth nur via Session-Cookie. |
 | P0-2 | Destruktive Migrationen | ✅ Behoben | Migration 0021 benennt Tabellen um (`*_old`). Migration 0044 repariert RLS. |
 | P0-3 | Plugin-Upload RCE | ✅ Neutralisiert | Alle Upload-Endpoints deaktiviert (403). `_extract_plugin_from_zip()` ist Dead Code. |
 | P0-4 | RLS nicht erzwungen | ✅ Behoben | Migration 0028 setzt FORCE RLS. Migration 0044 erstellt `crm_runtime` (NOSUPERUSER, NOBYPASSRLS). |
 | P0-5 | Plugin-Doppelregistrierung | ✅ Behoben | Routen nur in create_app(). require_active_plugin() prüft Aktivierungsstatus. |
 | P0-6 | Kein persistentes Volume | ✅ Behoben | docker-compose.yml hat volumes für PostgreSQL, Redis, App-Uploads, Worker. |
 | P0-7 | Öffentliche Domain | ✅ Behoben | Keine crm.media-on.de Referenz mehr in docker-compose.yml. |
 ### Weitere verifizierte Behebungen
 - **B1** (doppelte get_redis()): ✅ Nur eine Definition in `app/core/auth.py` Zeile 53
 - **B3** (UploadFile response_model): ✅ `response_model=None` in dms, calendar, mail routes
 - **B7** (Webhook SSRF): ✅ Private IP-Check, `follow_redirects=False`, Protokoll-Check
 - **B9** (AUTH_SECRET vs SECRET_KEY): ✅ `.env.docker.example` verwendet `SECRET_KEY`
 - **B10** (Redis-Default-Passwort + Ports): ✅ Ports auskommentiert, Redis-Passwort required
 - **WebSocket Auth**: ✅ Beide WS-Endpunkte haben `verify_ws_origin()`, Session-Cookie-Validierung, `user_id` aus Session

 ## Phase 6: Manifest-Anpassung & Konsolidierung
 **Ziel:** Alle in Phase 4 und 5 definierten Manifest-Felder werden ins `PluginManifest` integriert, bestehende Manifeste aktualisiert, und das Manifest-System finalisiert.
 **Wichtig:** Diese Phase baut auf Phase 4 (Versioning) und Phase 5 (Marketplace) auf und muss als letztes durchgeführt werden.
 ### 6.1 PluginManifest erweitern (4 Std)
 **Aktuelles Manifest (verifiziert 2026-07-26):**
 ```python
 class PluginManifest(BaseModel):
    name: str
    version: str
    display_name: str
    description: str
    dependencies: list[str]
    routes: list[PluginRouteDef]
    events: list[str]
    migrations: list[str]
    permissions: list[str]
    is_core: bool
    field_definitions: list[FieldDefinition]
    agent_capabilities: list[str]

    miniapps: list[MiniAppContribution]
    custom_fields: list[CustomFieldDefinition]
    model_config = {"extra": "forbid"}
 ```
 **Neue Felder hinzufügen:**
 ```python
 class PluginManifest(BaseModel):
    # ... alle bestehenden Felder ...
    # ── Versioning (Phase 4) ──
    min_app_version: str = Field(
        default="0.0.0",
        description="Minimum LeoCRM version required (SemVer)"
    )
    # ── Marketplace (Phase 5) ──
    author: str = Field(default="", max_length=200, description="Plugin author name")
    author_email: str = Field(default="", max_length=200, description="Author contact email")
    homepage: str = Field(default="", max_length=500, description="Plugin homepage URL")
    license: str = Field(default="MIT", max_length=50, description="License identifier")
    icon: str = Field(default="", description="Icon URL or emoji")
    screenshots: list[str] = Field(default_factory=list, description="Screenshot URLs for marketplace")
    changelog: str = Field(default="", description="Changelog URL or inline text")
    marketplace_tags: list[str] = Field(default_factory=list, description="Marketplace category tags")
    price: float = Field(default=0.0, ge=0.0, description="Price (0 = free)")
    # ── Hooks (Phase 2) ──
    hooks: list[str] = Field(
        default_factory=list,
        description="Hook names this plugin registers (e.g. 'contact.before_create')"
    )
    # ── Contracts (Phase 1) ──
    contract_version: str = Field(
        default="1.0.0",
        description="Contract API version this plugin exposes"
    )
 ```
 ### 6.2 Manifest-Schema-Dokumentation aktualisieren (3 Std)
 **`MANIFEST_SCHEMA_DOC` in `manifest.py` erweitern:**
 - Alle neuen Felder in `fields`-Dict aufnehmen
 - `example`-Manifest mit neuen Feldern aktualisieren
 - API-Endpoint `GET /api/v1/plugins/manifest` liefert vollständiges Schema
 ### 6.3 Alle 19 Plugin-Manifeste aktualisieren (8 Std)
 Jedes Plugin-Manifest muss um die neuen Felder erweitert werden:
 | # | Plugin | Aufwand | Neue Felder |
 |---|---|---|---|
 | 1 | `ai_assistant` | 30 Min | author, min_app_version, hooks, contract_version |

 **Muster für Aktualisierung:**
 ```python
 # VORHER:
 manifest = PluginManifest(
    name="calendar",
    version="1.0.0",
    display_name="Calendar",
    ...
 )
 # NACHHER:
 manifest = PluginManifest(
    name="calendar",
    version="1.0.0",
    display_name="Calendar",
    # ... bestehende Felder ...
    # ── Neue Felder ──
    min_app_version="1.0.0",
    author="LeoCRM Team",
    license="MIT",
    hooks=["calendar.before_appointment", "calendar.after_appointment"],
    contract_version="1.0.0",
 )
 ```
 ### 6.4 Frontend Plugin-Manifest-Typen aktualisieren (2 Std)
 **`frontend/src/api/pluginManifests.ts` und `frontend/src/types/automation.ts`:**
 - TypeScript-Interfaces um neue Manifest-Felder erweitern
 - `PluginManifestResponse`-Typ aktualisieren
 - Frontend-Komponenten die Manifest-Felder anzeigen erweitern
 ### 6.5 Manifest-Validierung verschärfen (3 Std)
 **Neue Validierungsregeln in `PluginManifest`:**
 ```python
@field_validator("min_app_version")
@classmethod
 def validate_min_app_version(cls, v: str) -> str:
    """Validate SemVer format."""
    from app.plugins.semver import SemVer
    SemVer.parse(v)  # Raises ValueError if invalid
    return v
@field_validator("hooks")
@classmethod
 def validate_hooks(cls, v: list[str]) -> list[str]:
    """Validate hook names follow namespace.pattern."""
    for hook in v:
        if not re.match(r"^[a-z_]+\.[a-z_]+$", hook):
            raise ValueError(f"Invalid hook name '{hook}': must be 'namespace.action'")
    return v
 ```
 ### 6.6 Tests für erweitertes Manifest (3 Std)
 - `test_manifest.py` — Neue Felder validieren
 - `test_manifest_validation.py` — SemVer-Validierung, Hook-Name-Validierung
 - Alle Plugin-Tests: Manifest mit neuen Feldern erstellen
 - Frontend-Tests: Manifest mit neuen Feldern rendern
 ### Meilenstein Phase 6:
 - ✅ `PluginManifest` hat alle neuen Felder (min_app_version, author, hooks, contract_version, etc.)
 - ✅ `MANIFEST_SCHEMA_DOC` ist vollständig aktualisiert
 - ✅ Alle 19 Plugin-Manifeste haben die neuen Felder
 - ✅ Frontend-Typen sind aktualisiert
 - ✅ Manifest-Validierung ist verschärft
 - ✅ Tests bestanden

 ---
 ## Was erledigt ist
 ### Phase 0+1 (Security & RLS)
 - 5 DB-Rollen mit separaten Verbindungen
 - RLS fail-closed auf 108 Tenant-Tabellen
 - FORCE ROW LEVEL SECURITY aktiviert
 - 0 legacy app.tenant_id Policies
 - Plugin-Migrationen über crm_migration (DDL)
 - Worker per-Tenant Outbox-Processing mit RLS-Kontext
 - Event-Handler nur für aktive Plugins
 - Passwort-Reset end-to-end mit SMTP getestet
 - Leere DB-Installation ohne manuelle Eingriffe
 - Restore + Upgrade verifiziert
 - Coolify Redeploy/Stop/Start funktioniert ohne manuelles Eingreifen
 ### Phase 2 (Datenintegrität)
 - 74 FK-Constraints (tenant_id → tenants.id ON DELETE CASCADE) hinzugefügt
 - 10 globale Tabellen ausgeschlossen
 - Orphan-Cleanup durchgeführt
 - FK-Tests auf Produktion: INSERT mit ungültiger tenant_id blockiert ✅
 ### Phase 3 (Plugin-Lifecycle)
 - 14 Tests: Registry, Lifecycle, Idempotency, Dependencies, Core-Schutz
 - Plugin-Lifecycle war bereits korrekt implementiert
 - Tests bestätigen: activate → deactivate → reactivate funktioniert
 ---
 ## Was als nächstes zu tun ist
 ### Phase 5 (Outbox) — abgeschlossen (produktionsverifiziert)
 - Per-Tenant Outbox-Processing (Gate 5)
 - Dead-Letter-Queue: error_message + failed_at Spalten, Replay-Funktionen
 - Monitoring: /api/v1/outbox/stats, /failed, /consumer-registry Endpoints
 - Consumer-Registry: outbox_deliveries pro Consumer-Handler geschrieben
 - Processing-Recovery: recover_stuck_events (stuck processing -> pending)
 - Retention-Cleanup: cleanup_published_events (hourly cron job, 30 days)
 - Replay setzt outbox_deliveries zurueck (clean retry)
 - 23/23 Unit-Tests + Produktions-Verifikation:
  - outbox_deliveries: 4 Eintraege mit status=delivered
  - recover-stuck: 200, 0 stuck events
  - cleanup-published: 200, 22 alte Events geloescht
  - consumer-registry: 200, alle Handler gelistet
  - failed: 200, 0 failed events
  - stats: 200, korrekte counts
 - deploy.py repariert: Worker-Deploy funktioniert jetzt korrekt
 ### Phase 7 (DMS/Attachments) — nicht begonnen
 - Streaming Upload/Download
 - Deduplikation tenantlokal
 - Keine Cross-Tenant-Dateireferenzen
 - Aufwand: 10–16h
 ### Phase 4 (KI-Delegation) — nicht begonnen
 - Delegation-Contract, Tenant-scoped Permissions
 - Audit, Rollback, Approval
 - Aufwand: 10–16h
 ### Phase 6 (Workspaces) — abgeschlossen (produktionsverifiziert)
 - Backend: Widget CRUD (create, list, update, delete), Manager-Role-Check, Cross-Tenant-Validierung
 - Default-Workspace Seeding (12 Standard-Module), Set-User-Default-Workspace
 - Fix: create_workspace Default-Uniqueness (unset others before insert)
 - Frontend: workspaceStore (Zustand) mit sessionStorage Persistenz
 - API-Client Interceptor: X-Workspace-ID Header auf allen Requests
 - useWorkspace hook auf workspaceStore umgestellt
 - Widget API hooks: useWorkspaceWidgets, useCreateWorkspaceWidget, etc.
 - Settings-Route: /settings/workspaces mit WorkspaceManagerPage
 - 25 Backend-Tests + 12 Frontend-Tests (alle bestanden)
 - Produktions-Verifikation:
  - 2 Workspaces (Verkauf/Einkauf) mit unterschiedlichen Modulen ✅
  - Hidden module (calendar in Einkauf) nicht in Context ✅
  - Multiple widgets mit gleichem key (2x recent_contacts) ✅
  - Widget CRUD: create, update, delete ✅
  - Set-default: Workspace-Wechsel funktioniert ✅
  - Manager-Role: Creator ist Manager ✅
  - Cross-Tenant: RLS isoliert Workspaces pro Tenant ✅
 ### Phase 8–10 — nicht begonnen
 - Sicherheitsreste, CI, Backup/Monitoring
 - Aufwand: 38–66h

 ## Wichtige Regeln für den nächsten Agenten
 1. **Keine manuellen Docker-Befehle** — alles über Coolify API oder deploy.py
 2. **Repo lesen bevor ändern** — docker-compose.yml und deploy.py beachten
 3. **Migrationen sind Forward-Only** — keine alten Migrationen verändern
 4. **RLS ist fail-closed** — kein Tenant-Kontext = kein Zugriff
 5. **crm_api hat keine DDL-Rechte** — Plugin-Migrationen über get_migration_engine()
 6. **Worker ist Coolify Service** — UUID asxqaq3566to108xordck0ff
 7. **Alle DB-Passwörter sind identisch** — siehe .env.docker.example
 8. **pgvector/pgvector:pg16** als DB-Image — nicht postgres:16-alpine
 9. **Tests müssen mit echten unprivilegierten Rollen laufen** — nicht mit Superuser
 10. **Jede Phase: analysieren → implementieren → migrieren → testen → dokumentieren**

 (bootstrap circle: Login → Membership → Tenant-Context → Login).
 RLS on these tables blocks login because there's no tenant context yet.
 Solution: Disable RLS on system identity tables. Tenant isolation for
 these tables is enforced at the application level (auth_service always
 filters by user_id + tenant_id in queries).

 """Restore tenant RLS, transfer ownership, fix roles and grants.
 This migration implements Phase 1 of the Sanierungsplan:
 1. Transfer ALL table ownership from crm_user (SUPERUSER) to crm_migration (NOSUPERUSER, NOBYPASSRLS)
 2. ALTER ROLE crm_migration NOBYPASSRLS
 3. Enable RLS + FORCE on ALL tenant tables (tables with tenant_id column)
 4. Drop ALL old policies (scoped to {public} or using non-NULLIF patterns)
 5. Create new fail-closed policies scoped to {crm_api, crm_worker}
 6. Revoke excessive grants from crm_runtime, crm_worker, crm_api, crm_auth
 7. Grant proper minimal permissions to crm_auth (identity tables only)
 8. Grant CRUD to crm_api and crm_worker on tenant tables
 9. Revoke alembic_version access from crm_api and crm_worker
 10. Set default privileges for crm_migration owner
 11. Drop crm_runtime legacy role
 12. Create crm_platform_admin role (for one-time infrastructure only)
