fix(share): self-host og:image so link previews stay reliable

Browse source 
A remote thumbnail as og:image is unreliable for the crawler — Facebook's signed
CDN URL expires (so an old shared link's image later vanishes) and cross-origin
hotlinking is flaky. Record a self-hosted poster for EVERY download (ensure_poster
returns the existing <base>.jpg thumbnail sidecar, or cuts a frame) and point
og:image at our own /api/public/watch/{token}/poster.jpg. Backfill now fills
poster_path for all existing downloads, not just thumbnail-less ones.
