fix(tests): fix two failing tests - missing DB table and MagicMock IP address

- tests/test_database.py: add user_imap_accounts table to the regression
  test's initial DB setup (migration 022 creates it before rev 026, so it
  must exist for migration 032's ALTER TABLE to succeed)
- tests/test_local_auth.py: configure mock_request.headers.get to return
  None and client=None so get_client_ip() returns "unknown" instead of an
  un-serialisable MagicMock that broke the audit_logs INSERT in
  test_local_login_success and test_local_login_by_email
