fix: resolve multiple test failures in imap_tasks, main lifespan, and API settings endpoints

- Add _require_admin + AdminUser dependency to google_drive.py, dropbox.py, onedrive.py
  and switch save-settings endpoints from @require_login to Depends(_require_admin) so
  tests can use dependency_overrides to bypass auth
- Wrap lifespan shutdown section (logging.info + notify_shutdown) in try/except to
  silence OSError and other exceptions during shutdown (test_lifespan_shutdown_*)
- Add @patch("app.tasks.imap_tasks.is_private_ip", return_value=False) to 5 IMAP
  tests that use imap.example.com (unresolvable in CI, causing is_private_ip to return
  True and pull_inbox to return early before any IMAP operations)
