Fix compilation errors, update Gradle, and refactor code

This commit addresses several issues and improvements:

- **Gradle Update:** Upgraded Gradle wrapper to version 8.14.3.
- **CI Fixes:**
    - Resolved compilation errors in `SupportRepository.java` by updating the `queryProductDetailsAsync` callback to correctly handle the `productDetailsList`.
    - Corrected the usage of `Gravity.START` to `GravityCompat.START` in `NavigationDrawerActivity.java`.
- **Code Refactoring:**
    - Replaced the deprecated `onBackPressed()` method in `MainActivity.java` with the newer `OnBackPressedCallback`.
    - Converted the `PromotedApp` class to a Java record for conciseness.
    - Removed unused private `binding` fields from several Fragment classes.
    - Added a null check for the `preference` parameter in `MainRepository.java` to prevent potential `NullPointerExceptions`.
- **Localization:** Fixed a typo in the German translation for `summary_preference_faq_4`.
