feat(player): skipping an episode marks it watched, not paused

Skipping to the next episode left a mid-episode resume point behind, so
the skipped episode reappeared in Continue Watching with a partial
progress bar. Skipping means "done with this one", not "stopped here".

- reportSkippedEpisode marks the outgoing episode played instead of
  reporting a stop position, and arms a one-shot suppression consumed by
  the player's stop handler, so VideoPlayer's post-navigation unmount
  stop report can't overwrite the 100% progress with the partial one.
- Continue Watching drops resume entries superseded by Next Up: an
  in-progress episode whose series has a next-up entry strictly later in
  series order (season, then episode) is hidden from the Home and TV
  rows. Movies, series without a next-up entry, and items with unknown
  or mixed ordering are always kept.

Adds UR-059, DR-088, DR-089.
