Previously the episodes table held only what the server has (all 'Owned'), so the
detail page never showed what you're missing. Now the metadata provider defines
the full series structure and the server marks ownership:
- TMDB returns the full season list (poster optional) + full episode fields
(title/air date/runtime/still/rating) per season.
- backfill_episodes UPSERTs: owned episodes keep has_file=1; episodes the server
lacks are inserted as MISSING (has_file=0); fully-missing seasons get created.
The cascade now iterates every TMDB season, not just the ones on the server.
- The scan prune only removes SERVER-originated rows (server_id set) that vanished,
so enrichment-added missing episodes/seasons are never pruned on re-scan.
Season coverage (X / Y) is now meaningful, and the episode list shows Owned +
Missing together. Seam tests: missing-episode insert, fully-missing season,
prune preserves missing.
