feat(5.1): add API audit document covering all 158 UI functions across 24 categories

- Create docs/api-audit.md with systematic mapping of UI functions to API endpoints
- Audit covers: Contacts, Calendar, DMS, Mail, Notifications, Users/Roles, Groups,
  Tags, Workflows, Automation/Agents, AI Assistant, AI Proactive, AI UI Control,
  Communication, Unified Search, Plugins, Settings, Import/Export, Entity History,
  Audit Log, Attachments, Addresses, UI State (sidebar/tab/filter)
- All 158 UI functions have corresponding API endpoints (0 missing)
- UI state persistence (sidebar, theme, locale, active tab, sort) covered by Task 5.2
- Frontend API module coverage table maps all 25 frontend modules to backend routes
- RBAC coverage documented for all endpoints
- Add 9 tests verifying audit document structure and endpoint reachability

+| `api/permissions.ts` | `app/plugins/builtins/permissions/routes.py` | ✅ |
+
+## RBAC Coverage
+
+All API routes use `require_permission()` dependency for RBAC enforcement:
+- Core routes: `contacts:read`, `contacts:write`, `users:read`, `users:write`, etc.
+- Plugin routes: `dms:read`, `dms:write`, `dms:delete`, `dms:share`, `calendar:read`, `calendar:write`, etc.
+- User preferences: `user_preferences:read`, `user_preferences:write` (added in Task 5.2)
+- Admin role (`*:*` wildcard) has access to all endpoints
+- Editor and viewer roles have scoped permissions per module
+
+## Conclusion
+
+All 158 UI functions across 24 categories have corresponding API endpoints. No missing endpoints
+were identified. The User Preferences API (Task 5.2) fills the previously missing UI state
+persistence gap (sidebar, theme, locale, active tab, sort preferences).
