fix: improve apple intelligence ui and add reusable alert component (#517)

- hide model dropdown when apple intelligence is selected
- move error state into provider section (only shows when unavailable)
- remove redundant apple intelligence infobox
- add reusable Alert component with variants (error, warning, info, success)
- Alert supports contained prop for use inside settings groups
