fix(radio): show ICY track in OS media controls (#816) (#924)

* fix(radio): show ICY track in OS media controls (#816)

Internet radio streams through the WebView <audio> element, for which
WebKitGTK registers its own MPRIS player — the one Linux desktops show.
souvlaki metadata pushes were overridden by it, so the OS overlay only
ever showed the app name. Feed the resolved ICY/AzuraCast metadata to
that player via navigator.mediaSession (and mirror to souvlaki), so the
overlay updates per track. Falls back to the station name when a stream
sends no metadata.
