Enrich playlist video dates after indexing

Browse Source 
flat-playlist mode returns timestamp=null for most playlist entries so
published_at is missing after the initial index. Now kicks off
_enrich_missing_task (scoped to the playlist size) as a daemon thread
immediately after indexing commits, filling in dates and view counts
in the background via individual video fetches.
