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)

Module Integration:
- RVW module integrated with PromptService (editorial + methodology)
- All modules (RVW/PKB/ASL/DC) added authenticate + requireModule middleware

Database Changes:
- Added platform_schema.modules table
- Modified tenant_modules table (added index and UUID)
