feat(mobile): Add highlights page to mobile app (#2156)

* feat: Add highlights page to mobile app

This commit adds a new highlights page to the mobile app where users can
view all their highlights with the following features:

- HighlightCard component: Displays individual highlights with colored borders,
  text, optional notes, timestamps, and a link to the source bookmark
- HighlightList component: Renders a scrollable list of highlights with
  pull-to-refresh and infinite scroll pagination
- UpdatingHighlightList component: Handles data fetching using tRPC infinite
  queries with automatic cache invalidation
- New /dashboard/highlights route with large header title
- Added navigation link in Settings tab under "App Settings"

All components follow the existing mobile app patterns and integrate with
the existing highlights API.

* make it a tab
