Fix critical bug: remove TappableOverlay that was blocking all button clicks

The TappableOverlay was added to the entire stage container, which
made it cover the video AND all control buttons below. This invisible
overlay intercepted all mouse events, preventing buttons from working.

Temporarily disabled the overlay to restore button functionality.
Will need to reimplement properly as floating controls that only
overlay the video area, not the UI controls.

Fixes:
- Play/pause button now clickable
- Volume controls now work
- All other UI buttons functional
- Keyboard shortcuts (Space, F11, ESC) still work
