Add scheduled tariff synchronization and bulk update functionality

- Introduced `runScheduledSyncTariffs` function to handle tariff synchronization independently from VPS and payment sync.
- Updated `syncFromBillmanager` to accept options for skipping tariff and VPS payment syncs.
- Added new database columns for `syncTariffsIntervalMinutes` and `customFields` in settings.
- Enhanced settings page to configure tariff sync interval.
- Implemented bulk update functionality for VPS status and deletion in the VPS management page.
- Updated various components to support new features, including sync log display and improved payment handling.
