Add URL routing and enhanced mobile terminal controls

- Implement browser URL routing with session ID parameters
- Add browser back/forward navigation support
- Auto-load session view from URL on page refresh
- Add mobile swipe-back gesture from left edge
- Reorganize mobile controls: arrow keys + special keys in normal view
- Simplify text overlay to show only SEND and SEND+ENTER buttons
- Remove left arrow from BACK button for cleaner look
