Refactor: Update edge-to-edge implementation for Android 15

This commit updates the `applyEdgeToEdge` logic in `BaseActivity` to target Android 15 (Vanilla Ice Cream) and above.

Key changes include:
- Restricting `setDecorFitsSystemWindows` and inset listeners to `SDK_INT >= VANILLA_ICE_CREAM`.
- Switching the inset listener from the content view to the `decorView`.
- Accounting for IME (keyboard) insets when calculating bottom padding.
- Updating padding logic to include left and right system bar insets.
