CI / test (push) Has been cancelled
fix(home): preview tracks frame state even with locked images and 304 polls
Three problems were stacked:

1. The 200 serving path didn't set currentImage when a locked image was
   served (RotationService.advance bypassed). The frame got the locked
   photo; the DB kept the previous one; Home showed the old one.

2. The 304 path didn't flush at all. lastSeenAt (markSeen) was lost on
   every no-change poll, and any drift in currentImage couldn't self-heal.
   For a frame that's been locked for a while, polls cycle as 304 forever
   and the DB stays wrong indefinitely.

3. Pull-to-refresh fetched via fetchDevices(), which flips loading=true
   and replaces the cards with "Loading…" mid-fetch. The PTR spinner was
   working but users couldn't see the result of their refresh.

Fixes:
- Both 200 and 304 paths now set currentImage = $image and flush. The
  304 path becomes self-healing for any device whose currentImage drifted
  from reality (e.g., from before the 200-path fix).
- fetchDevices / fetchImages take an optional { silent: true } that
  skips toggling loading.value. PTR refresh callbacks pass silent so
  the cards stay visible during background refresh.
- HomeView also listens on visibilitychange and silently re-fetches when
  the PWA returns to foreground, so reopening the app shows current
  state without a manual pull.
