jtrzupek c154deab37 feat(sources): 0-5★ ranking on Sites (freshness/metadata/plays) + playback telemetry
Rates each source on three axes the user asked for:
- freshness: how recently/often new content arrives (newest age + 7d volume)
- richness: metadata coverage (thumbnail/tags/performers/description/studio/duration)
- plays: does it actually play — from real playback telemetry when available,
  else a proxy from the resolve mechanism. 0★ = offline (gates the overall stars,
  so a fresh+rich source that doesn't play still ranks bottom — the hqfap/4k69 case)

Backend:
- playback_events: fire-and-forget telemetry POST from the app per playback attempt
  (origin + success/error + time-to-first-frame), append-only, 30d retention
- source_stats: per-origin computed scores, refreshed by a scheduler job (6h);
  /sources joins it and sorts by stars
- models + local migration 0025; new GOON_SCHED_SOURCE_STATS_HOURS setting

Mobile:
- Sites rows show ★ rating; tap the stars for a breakdown (axes + metadata %, plus
  whether "plays" is measured or estimated)
- PlayerScreen reports playback success/failure per source (native path only —
  symmetric, conservative); origin threaded through Scene/Movie play callsites

"""Playback telemetry — fire-and-forget ping z apki po każdej próbie odtwarzania.
Po co: ranking źródeł (Sites screen) potrzebuje realnego sygnału "czy to gra".
Świeżość i bogactwo metadanych liczymy z DB, ale "szybkość działania" znał tylko
telefon (resolve hosterów/WebView dzieje się phone-side). Bez tego sygnału źródło
może wyglądać świeżo i bogato, a serwować stub (problem hqfap/4k69).
Append-only, agregowane przez `run_source_stats` (okno 7d → health score per origin).
Retencja: stats-job kasuje wpisy starsze niż 30 dni. Brak FK na scene (scene_id
informacyjne, scena może zniknąć przez dedup/merge).
