Release v0.1.2

This release introduces significant quality-of-life improvements for adding games, a revamped Settings screen, and several important bug fixes.

✨ Highlights

One-Tap Sharing from SteamDB: The in-app browser for steamdb.info now features a dedicated action button. You can now send a game's AppID directly back to Mjolnir with a single tap, completely removing the need to use the browser's general share function for this workflow.
Revamped Settings Screen: The Settings menu has been modernized with a top app bar and a back button. The entire screen is now scrollable, ensuring a consistent and accessible experience on all screen sizes, especially in landscape mode.

Share Intent Repaired: The standard "Share to Mjolnir" functionality from external browsers has been fixed and now correctly processes URLs.
Code Health: Resolved deprecation warnings to maintain a clean and modern codebase.
Documentation: The README.md and CHANGELOG.md have been updated to reflect all the latest changes.
