fix(ui): right rail review follow-ups for Radio reveals and CCTV restores

- A Radio pick reopens a closed Context around an expanded Radio section in
  every HUD layout, not only Cyber.
- The Radio reveal's scrollend landing gives way to a user scroll, key or
  pointer, and stops after two seconds.
- The compact player's Details button scrolls the Radio section and its
  Enable into view inside Context.
- A camera layer switched on by a share link or a saved session no longer
  opens the CCTV panel over the restored tab; a user switch-on still does.
