logout method
Signs the user out by calling the logout endpoint and cleaning up local auth data.
Server-side logout failures are swallowed — local cleanup always proceeds. Emits AuthenticationStatus.unauthenticated before clearing data to prevent a transient authenticated-with-empty-user state.
Implementation
Future<void> logout() async {
_logger.info('[AuthRepository] Logout requested');
try {
// TODO: swap getDummyLogout() → logout() when API is ready
await _authService.getDummyLogout();
} catch (e, st) {
_logger.warn('[AuthRepository] Server logout failed (continuing local cleanup)', error: e, stackTrace: st);
}
await _forceLogout();
}
