feat(admin): Complete tenant management and module access control system

Major Features:
- Tenant management CRUD (list, create, edit, delete, module configuration)
- Dynamic module management system (modules table with 8 modules)
- Multi-tenant module permission merging (ModuleService)
- Module access control middleware (requireModule)
- User module permission API (GET /api/v1/auth/me/modules)
- Frontend module permission filtering (HomePage + TopNavigation)

Module Integration:
- RVW module integrated with PromptService (editorial + methodology)
- All modules (RVW/PKB/ASL/DC) added authenticate + requireModule middleware
- Fixed ReviewTask foreign key constraint (cross-schema issue)
- Removed all MOCK_USER_ID, unified to request.user?.userId

Prompt Management Enhancements:
- Module names displayed in Chinese (RVW -> 智能审稿)
- Enhanced version history with view content and rollback features
- List page shows both activeVersion and draftVersion columns

Database Changes:
- Added platform_schema.modules table
- Modified tenant_modules table (added index and UUID)
- Removed ReviewTask foreign key to public.users (cross-schema fix)
- Seeded 8 modules: RVW, PKB, ASL, DC, IIT, AIA, SSA, ST

Documentation Updates:
- Updated ADMIN module development status
- Updated TODO checklist (89% progress)
- Updated Prompt management plan (Phase 3.5.5 completed)
- Added module authentication specification

Files Changed: 80+
Status: All features tested and verified locally
Next: User management module development
