fix(player): resume replay, TV surface recovery, and finite time guards

ExoPlayer:
   - Pass the resume position into setMediaSource() instead of prepare()-ing
     from 0 and then seekTo()-ing, which replayed the first few seconds before
     jumping to the resume point.
   - Drop the redundant initial seek that mirrors the resume position (fired by
     the JS direct-player layer once tracks are ready). ExoPlayer re-buffers on
     every seek — even a no-op to the current position — so it stuttered startup.

   MPV (Android TV):
   - Recover the video pipeline when returning from the screensaver / app
     background while paused. TV uses zero-copy hwdec=mediacodec, which binds
     MediaCodec directly to the display surface; when the screensaver invalidates
     that surface the decoder is left bound to dead buffers and mpv disables the
     video track. Register TV-only activity-lifecycle callbacks and reload at the
     cached position on resume to recreate the decoder against the live surface
     (Android counterpart to iOS's performDecoderReset()).

   Video time controls:
   - Initialize remainingTime to 0 instead of Infinity and guard non-finite
     values, so the first paint shows "0:00" (and "—" for the end time) rather
     than "Infinityh NaNm NaNs" and an Invalid Date before the first progress
     update
