fix: AI settings persistence and UI improvements

Bug Fixes:
- Fix boolean fields with 'omitempty' not persisting false values
  - AlertTriggeredAnalysis, PatrolAnalyzeNodes/Guests/Docker/Storage
  - omitempty causes Go to skip false (zero value) when marshaling JSON
  - On reload, NewDefaultAIConfig() sets true, and missing field stays true

- Fix model dropdown losing selection after save (SolidJS reactivity issue)
  - Added explicit 'selected' attribute to option elements
  - Ensures browser maintains selection with optgroups during re-renders

Improvements:
- Change patrol type label from 'Quick' to 'Patrol' in history table
- Add chat_model and patrol_model to AI settings update log
- Add alert_triggered_analysis to AI config load log for debugging
