Fix iOS playback settings menu text disappearing and resizing issues

When tapping menus in playback settings (playback mode, quality profile,
stream, rate, captions, audio track), the selected value text would
disappear and cause unwanted resizing animations.

Implemented ZStack overlay technique for all iOS menu buttons:
- Visible static label remains on screen
- Invisible Menu overlay (.opacity(0)) handles tap interactions
- Prevents text from disappearing when menu opens
- Eliminates resizing animations on option selection
