Auto-load Autotask reference data on settings page load

Fixed issue where Default Ticket Status dropdown was empty when
opening the settings page. Now automatically loads reference data
(queues, sources, statuses, priorities) when:
- Autotask integration is enabled
- API credentials are configured
- Reference data cache is empty

This eliminates the need to manually click "Refresh reference data"
before being able to select a default ticket status.
