feat: Add JWT auth and nomenclature sync to data-entry-app

Integrate shared JWT authentication into data-entry-app:
- Add Oracle pool initialization for auth service
- Add AuthenticationMiddleware to protect API routes
- Update all receipt endpoints to use CurrentUser from JWT
- Add shared auth router (/api/auth/login, /api/auth/refresh)

Add nomenclature synchronization feature:
- Create SQLite models for synced suppliers, local suppliers, and cash registers
- Add nomenclature router with sync triggers and CRUD endpoints
- Add sync service for Oracle → SQLite nomenclature data
- Update nomenclature_service to use synced SQLite data with fallbacks

Create shared frontend components:
- Add shared/frontend/ with LoginView.vue, auth store factory, login.css
- Integrate shared login and auth into data-entry-app frontend
- Add axios-based API service with token refresh interceptor
