fix(live): returning from playback keeps the group you were in

The rail opens whatever gets focused, so when the player closed and focus
landed on "Alle Sender", the view silently switched away from the group
the viewer had been browsing. A restore flag now suppresses that
auto-select until focus has been placed on the channel that was watched.

Completes #13.
