Enhance UI layout and text wrapping

- Added margins to `search_results_scrolled` in `MainWindow.vala` for better spacing.
- Removed unnecessary horizontal alignment from `bubble` in `MainWindow.vala`.
- Adjusted string concatenation formatting in `MainWindow.vala` for readability.
- Enabled horizontal expansion for `place_name` and `place_location` labels in `LocationResult.vala` to improve text wrapping.
