fix(i-d): RBAC-Comprehensive 4 Failures behoben — http_exception_handler um dict-detail-Durchreichung erweitert (strukturierte Error-Codes AGENTS.md-konform, body[detail] = raw_detail dict statt stringify); 3 Contact-Payload-Feldnamen korrigiert (firstname/surname statt first_name/last_name in legacy-editor Tests); test_rbac_comprehensive 102/102 gruen

Also fixes ARCH-029/041: none-check before attribute access in trigger dispatcher.

+- ~~9 Contact/Company-Test-Failures~~ ✅ GELÖST in D1-b (ContactCreate-Typ-Inferenz, 9d8da99) — Root-Cause war BUG-008-Validator-Default type='company'.
+- ~~test_mail: 28 Failures 'Unknown entity type: mail_account'~~ ✅ Root-Cause in D3-d behoben (ef90d57): Mail/DMS get_entity_models-Overrides fehlten; Rest-Failures im vollen Mail-Lauf = IMAP-Netzwerk-Calls ohne Mocking (Test-Infrastruktur-Follow-up, kein Produktionsbug).
+- 5 PluginLoader-Test-Failures sind Vorbestand (Stash-Verifikation): Tests erwarten UI-Text 'Failed to load plugin', aktueller Loader zeigt deutsche Texte.
+- Geister-Komponenten: Backend-Manifeste referenzieren @/pages/AIAssistant + 5 Contact-Detail-Tabs, die im Frontend nicht existieren (siehe unten).

+- Reparaturplan: docs/fix-plan-v3.md (Blöcke 0/H/A/B/C done, D gestartet, E/F/G offen)
+- Findings-Status: docs/test-bugs.md (✅/⏳ je Finding)
+- Verifikationsmuster: Stash-Test gegen Pre-Block-Commit für Vorbestands-Nachweis; Endpoint-Diff via OpenAPI-Snapshot; Cross-Plugin-Scan als Gate
+- Test-DB: .env.test (leocrm_test), automation-Tests erstellen eigene ephemere DBs
+- Forgejo-Issues/Milestones laut AGENTS.md §9 noch NICHT angelegt — nur PROGRESS.md-Tracking

+- @/components/contact/ContactCalendarTab, ContactFilesTab, ContactLinksTab, ContactMailTab, ContactTagsTab (calendar/dms/entity_links/mail/tags Detail-Tabs)
+Diese Tabs zeigen in Production den ErrorBoundary-Fallback.
+
+### Bekannte Vorbestände (Block D Triage)
+- 9 Contact/Company-Test-Failures existieren seit vor Block B (Stash-Verifikation 2026-08-23): KeyError 'id' bei Create/Delete/Link-Flows — Ursache ungeklärt, gehört zur pytest-Massen-Triage.
