feat: enhance global search and map experience

- Global Activity Search:
  - Allow searching activities globally (not just in destination).
  - Add distance warning for activities > 50km away.
- Create Trip UI:
  - Fix destination suggestion list overflow.
  - Prevent suggestion list from reappearing after selection.
- Map:
  - Add generic text search support (e.g., "Restaurants") on 'Enter'.
  - Display multiple results for generic searches.
  - Resize markers (User 60.0, Places 50.0).
  - Standardize place markers to red pin.
