docs(media): point plan/journal/park paths at .media-campaign and NeedsProcessing

The campaign-artifact home moved (42bc482) but the copy-paste surfaces still
named the old ones, and a tool's usage block is exactly what an agent runs:

- scripts/media-shows.py, media-tv.py, media-tvdupes.py: usage examples wrote
  plans and journals at the array root. media-apply.py defaults its journal to
  <root>/media-relayout.jsonl, so any run copied from those lines re-creates
  the root-level clutter the vault now forbids. Each block now names
  /mnt/entropy/.media-campaign/ and says why --journal is explicit.
- media-shows.py: --park named the retired media-park; the pile is
  /mnt/entropy/NeedsProcessing/TVShows.
- Jellyfin.md: library-coverage law named /data/media-park; names the pile by
  its current path and records when it moved.
- Media TV Relayout.md: the runnable --park path named media-park.

bats: 822 seams green.
