fix: pre-populate classifications instead of syncing from Autotask API

- Autotask REST API doesn't expose ClassificationIcons endpoint
- Created migration to populate 17 standard classification icons
- Removed sync button from UI (classifications are pre-loaded)
- Includes: Tools Only, Co-Managed, Wulf 365 Essentials, Partner, etc.
- Users can now select any classification to exclude from kiosk
