Refactor edge-to-edge handling and UI adjustments

This commit introduces several changes:

- Removes horizontal margins in `ad_about.xml`.
- Simplifies edge-to-edge implementation in `MainActivity.java` by directly using `WindowCompat.enableEdgeToEdge` when `useRail` is true, removing the custom `EdgeToEdgeDelegate` call for this case.
- Adds an assertion for `binding.progressBar` in `MainActivity.java` before setting its visibility.
- Implements `onMenuOpened` in `MainActivity.java` to ensure icons are visible in the `MenuBuilder`.
- Acknowledges FIXME comments in `EdgeToEdgeDelegate.java` related to deprecated methods for padding and margins.
