feat: compact relay status indicator on mobile

- Show only icon on mobile (44x44px touch target)
- Tap to expand for full details
- Smooth transition between compact and expanded states
- Maintains full display on desktop
- Reduces screen clutter on mobile while keeping info accessible

Flight mode notice now just shows airplane icon on mobile.
Tap it to see full connection details.
