Flutter half of offline-replay capture. Play events no longer
fire-and-forget: the reporter now tracks each play as a completed
unit (track, original start time, source, duration reached)
independently of connectivity.
- EventsApi.playOffline: single timestamp-preserving call → the new
/api/events play_offline (47aa178).
- MutationQueue: new play.offline kind + handler (EventsApi).
- PlayEventsReporter rework:
- _beginTrack captures start context + fires live play_started;
the server id is adopted only if it lands while still on-track.
- position progress gated on the tracked track id so a track
change can't clobber the finishing track's last values.
- _closeCurrent: if a server id registered, attempt the live
ended/skipped and fall back to the offline queue on failure; if
no id (offline start) enqueue the completed play directly. The
server applies the canonical skip rule, so the offline payload
only carries duration.
- app paused/detached closes durably via the queue (survives a
process kill; a teardown POST would not).
Result: listening to cached tracks fully offline now records
history / recs / scrobble / #415 rotation once back online, with
the original timestamps. Web stays best-effort by standing
occasional-use scope.
