#980. When the daily rebuild fires while a system-playlist detail page is
open, its cached data goes stale and can't be refetched in place — the
playlist id rotated, so the old id 404s. serverEvents now exposes a monotonic
rebuild counter; the detail page shows a "this mix was refreshed" banner with
a Refresh that re-resolves the variant (systemShuffle) to the new playlist id
and navigates there. No forced redirect, no auto-reload — the user refreshes
on their terms. Functional behaviors were already correct (tapping a song
plays it; tiles load the current mix); this closes the cosmetic list-staleness.

The web client only ever SENT events; it had no inbound SSE listener, so a
tab left open across the daily system-playlist rebuild kept showing
yesterday's home + playlist snapshots until a manual reload (the stale-
browse-view bug behind #968). Add useServerEvents(): opens /api/events/stream
while authenticated and, on playlist.system_rebuilt, invalidates the home,
playlists, and system-playlist-status query caches. Deliberately does not
disturb the active playback queue — that self-heals on the failure path.
Issue #968.
