Polish opponent select scene and restore category on return

- Replace flat title/subtitle pills with brass Plaque headers in OpponentSelectScene for visual consistency with the game menu
- Shift opponent scroll area down (OPP_SCROLL_TOP 155 -> 180, height 440 -> 415) to clear the subtitle plaque band
- Pass selected category back to GameMenu via scene.start data on Back so the active grid is restored instead of resetting to default
- Add GameMenuScene.init() to capture incoming category and reset stale instance props (_currentCategory, _gridAnim) since scene.start reuses the existing instance
- Guard fadeIn target list with .filter(Boolean) to skip any uncreated elements
