Introduce a one-time dialog to inform users that the app's name has been changed from "PixelPlay" to "PixelPlayer" due to a trademark issue.

This includes:
- A new `AppRebrandDialog` composable.
- Logic in `SettingsViewModel` and `UserPreferencesRepository` to track if the dialog has been shown.
- Displaying the dialog on the `HomeScreen`.

This commit introduces a complete overhaul of the Brick Breaker minigame with enhanced features and refines the trigger mechanism on the About screen.

**Brick Breaker Enhancements:**
*   **Dynamic Levels & Difficulty:** Implemented a level-based system where game speed increases and the paddle shrinks with each new level.
*   **New Brick Types:** Added "Hard" (multiple hits) and "Solid" (unbreakable) bricks.
*   **Improved Physics & Controls:** Refined ball-paddle collision for more dynamic angles and added slight speed boosts on paddle and brick hits.
*   **Visual Redesign:** Updated the entire game UI, including a modern dashboard, stats display, new game over/level complete screens, and improved visual effects for the paddle, ball, and bricks.
*   **Gameplay Loop:** Reworked game logic for starting new levels, resetting the game, and handling win/loss conditions more robustly.

**About Screen:**
*   Changed the easter egg activation from a triple-tap-and-hold gesture to a simpler long-press on the version number.
