Enhanced the floating control panel behavior:
- Ribbon smoothly fades out (opacity: 0) when panel expands
- Ribbon becomes non-interactive (pointer-events: none) when hidden
- Added smooth opacity transition (0.3s ease) for elegant fade effect
- Maintains consistent transition timing with panel slide animation
This eliminates the redundant ribbon icon when the full panel is visible,
creating a cleaner and less cluttered interface while maintaining the
intuitive expand/collapse interaction.
