Phase 1-2: Foundation + Admin Panel & Client Management

Phase 1 (Foundation):
- Project restructure (presenton-main → backend/ + frontend/)
- Database schema (8 new models, Alembic config, seed script)
- Auth (Azure AD SSO + dev bypass, JWT sessions, AuthMiddleware)
- RBAC (access_service, rbac_middleware, admin routers)
- Audit logging (fire-and-forget, AuditMiddleware, admin router)
- i18n (react-i18next with 5 namespace files)

Phase 2 (Admin Panel & Client Management):
- Admin panel shell (sidebar layout, role guard, 12 pages)
- Redux admin slice with 18 async thunks
- User management (role changes, deactivation)
- Client management (CRUD, brand config, team management)
- Brand config editor (colors, fonts, logos, voice rules)
- Master deck upload & parser (PPTX → HTML → React pipeline)
- Audit log viewer with filters and CSV/JSON export
