Claude 47bda040a2 Re-render when a screen leaves a sync group or a video wall
Taking a display out of a sync group, or deleting the wall it belonged to, froze it on whatever was
playing. The clip looped forever and every later refresh took the "unchanged" branch, because the
element was attached, playing and un-errored — healthy by every check the player makes. Only a
reboot cleared it.

On the web player, reconcileAdvanceTimerForMode re-arms a solo timer for widgets and images but
skips video and YouTube, on the grounds that they "self-advance via their own end handlers". The
handler that is live at that moment, though, was built for the mode being left: a group-rendered
video was created with `loop = !!groupSync`, a wall-follower video with `isFollower` true, and both
are captured in the closure at render time. A looping element never fires `ended`, and a follower's
handler declines to advance — so nothing self-advances and nothing re-renders. It now re-renders
whenever the element on screen is still looping, rather than guessing which media types can look
after themselves.

Tizen had the same freeze by a different route. GroupSyncController.exit and WallController.exit
both call player.invalidate() for exactly this purpose, but invalidate only cleared the change
signature — and load() returns at the continuity check ("current item survives, just retarget the
index") before reaching any render, so the invalidate was a no-op. It now forces the next load to
re-render, which is what those call sites always intended. On Tizen this froze every item type, not
just video, because `single` skips the timer in all of the renderers.
