Updated the naming of `styles.xml` and `themes.xml` to align with the new Android Studio template conventions. This follows up on commit `18c0143` where I introduced the new android studio project template.
- Verified and tested the changes thoroughly to ensure that the app behaves as expected, with no regressions.
- Ensured all affected references and dependencies were updated accordingly.
This keeps the project consistent with modern Android development practices and improves maintainability.
