Replaces the two organize-only triggers with a single reconcile_batch_playlists
called at both batch-completion points. It groups the batch's newly-resolved
tracks by their per-track playlist provenance:
- the batch's OWN organize playlist → full (re)build with prune, and
- a track that completed for a DIFFERENT playlist (e.g. a WISHLIST fulfilling a
track that belongs to an organize playlist) → ADDED to that folder, no prune.
So a late wishlist arrival now lands in its playlist folder immediately, instead
of only on the next sync/manual rebuild — the folder = the playlist's owned
members, kept true on every ownership change regardless of download path. Uses
the paths the batch already captured (no DB re-match, no waiting on the server
scan/sync). Non-fatal.
3 new reconcile tests (organize full-rebuild, wishlist add-without-prune, plain
batch no-op). 983 downloads/imports/playlist tests pass.
