	 * - opcje OAuth: yacht_booking_gcal_credentials, yacht_booking_gcal_tokens, yacht_booking_gcal_calendar_id, yacht_booking_gcal_sync_enabled
	 * - rezerwacje z _booking_source = 'ical_import' (per-yacht — nie odświeżane już)
	 * - stare crony OAuth + per-yacht iCal
	 *
	 * NIE kasuje:
	 * - _yacht_gcal_alias (aktywny dla globalnego importu)
