feat(ui): add profiles-only mode to simplify model selection

Adds a new setting to show only AI profiles by default, hiding advanced
model tweaking options (Claude SDK, thinking levels, Codex) for a cleaner
UI. Users can toggle advanced options when needed via "Show Advanced" button.

- Added showProfilesOnly setting in app store and settings view
- Modified board-view dialogs to conditionally hide advanced options
- Added toggle buttons to temporarily show advanced options in both
  add and edit feature modals
- Enhanced settings view with proper icons and descriptions
