feat: rewrite AuthService to use ROLAC auth API with in-memory token storage

- Replace GET /api/Token/Create (Basic Auth) with POST /api/Auth/login
- Add refresh() method using HttpOnly cookie (POST /api/Auth/refresh)
- Add initializeFromRefreshToken() for APP_INITIALIZER support
- logout() now fires POST /api/Auth/logout (fire-and-forget)
- Rename User interface to UserInfo (matches C# DTO: id, email, roles, languagePreference)
- All auth state is in-memory only (no localStorage)
- Fix downstream consumers: app.ts, header components, mfa-dialog, token-verification
- Fix tsconfig.spec.json: exclude legacy src/components and src/directives
- Add stub enums.model.ts and fix models/index.ts for pre-existing build errors
