Fix voice persistence and dynamic room link updates

Voice Persistence:
- Add voice/model saving to localStorage for persistent settings
- Load voice from URL → localStorage → default priority order
- Voice selection now persists across browser sessions and page refreshes

Dynamic Room Links:
- Add updateRoomLinksWithCurrentParams() function to update sidebar room links
- Room links now dynamically update with current username, model, and voice settings
- Both desktop and mobile room links stay synchronized with current parameters
- Fixes issue where clicking room links would lose user's current settings

Technical improvements:
- Enhanced syncInputsAndQueryString() to save to localStorage and update room links
- Initial sync call on page load ensures proper state from the start
- Maintains backwards compatibility with existing functionality
