trackers: media hub with webtoons, podcasts and videos; shows and anime filters

- /trackers/media: one card per child (reading, movies, shows, webtoons, music, podcasts,
  videos) with quick stats, a combined currently-consuming feed and a mixed watchlist
- webtoons, podcasts, videos: new owner-editable trackers on one generic media.items table,
  JSON import (owner form or scripts/media-run.sh)
- shows: /trackers/shows -> /trackers/movies?type=show; anime flag on movies.titles
  (backfilled, set from TMDB, owner toggle) and ?type=anime filter
- nav: media replaces the top-level reading, movies and music entries; their URLs are kept
