* fix(player): preserve volume when toggling mute
Muting now keeps the last volume level memorized. Unmuting restores that level, including amplified values allowed by the configured maximum.
* fix(player): preserve volume for companion remote mute
Route the companion remote through the shared mute transition so it no longer overwrites the persisted volume or restores to 100%. Also correct the Dartdoc formatting for the transition record fields.
Report the paused timeline every tick (~10s, matching official clients)
instead of every ~60s, and ping the Plex transcoder keepalive endpoint
alongside it while transcoding — PMS reaps idle transcode sessions that
timeline reports alone historically have not kept alive. Prevents the
transcode-variant of the #1520 stream death; the reporter's direct-play
case is covered by EOF classification and reconnect.
close#1520
Classify player EOF signals against the best-known duration: a mid-file
EOF means the stream died (transcode reaped or idle connection closed
during a long pause), not that the media ended — it must never mark the
item watched, prompt Play Next, or exit a movie. Recover with a bounded
in-place reload at the parked position; if the server is still refusing,
park on the old frame and rebuild the stream on user play/seek or when
the server-status monitor sees it come back online.
ffmpeg's reconnect gave up on the first HTTP-error response, so a PMS
answering 503 (startup maintenance) after an idle-pause disconnect
surfaced as a clean mid-file EOF instead of riding through the outage.
The old bool meant "attempt was current and handled", so callers could
not distinguish a real pre-open failure (old stream still loaded) from
success — the distinction the #1520 recovery needs.
