Previously the visible photo order was published only via a passive
useEffect on Timeline, which had a timing race: arrow nav in preview
could read a stale or empty sequence and fall back to the raw API
order, breaking visual order navigation in tag mode and after
filter changes.
Fix: openPreview now accepts an optional visibleSequence parameter,
and Timeline's onDoubleClick passes the freshly-computed flat
sequence directly. The store action adopts that sequence as the
authoritative visiblePhotoIds for the preview session, falling back
to the most-recently-published one for paths that don't have a click
site (e.g. the global Space hotkey).
The Timeline still publishes via useEffect for the Space-hotkey
fallback path, but the click path no longer depends on it.
