fix: pass missing biometricService to AppSessionController in tests

[Copilot]

AppSessionController was updated to require biometricService as a named parameter, but three test files that construct it were not updated accordingly, causing analysis errors.

Changes

• Added import 'package:classi/core/security/biometric_service.dart' to each affected test
• Passed biometricService: BiometricService() to every AppSessionController(...) call in:
  • test/app_entry_flow_test.dart
  • test/app_session_controller_test.dart
  • test/router_provider_test.dart

controller = AppSessionController(
  keyService: KeyService(),
  databasePathService: ...,
  securityPreferencesService: SecurityPreferencesService(),
  libraryBackupPreferencesService: LibraryBackupPreferencesService(),
  libraryBackupService: LibraryBackupService(),
  biometricService: BiometricService(), // added
);
