Fix garage automation triggers and improve presence handling

- Update leaving trigger to fire on any transition from "home" (not just to "not_home")
- Handle zone-based states (e.g. Arbeit, Dybbroparken) correctly
- Relax SnowyWhite tracker condition to allow non-"not_home" states (fixes blocking on "unknown")
- Improve reliability of presence-based garage control
