feat(library): show stored versions per episode and movie (LIBV-1)

- domain versionSpecOf: file name + ffprobe + ingest quality -> version spec;
  summarizeVersions; matchVersions (satisfied / missing / upgradeable, single target)
- GET /library/{id}/versions: per-season/episode versions, summaries, matches[]
- organize writes full spec into media_asset.delivery (specVersion 1)
- scripts/asset-spec-backfill.ts: dry-run by default, --probe local only, --apply
- web: season summary line, one-line spec per episode, N versions expand,
  tech info details (TODO: DEAI-2 TechInfo), movie versions panel
