Ingest and self-host company/network logos

CompanyBriefOut.logo_path and CompanyDetailOut.logo_path have existed
in the API schemas since Core 0.1's first pass, but nothing ever
actually populated them -- TMDb's production_companies/networks
entries carry a logo_path field that the normalizer simply never read,
so every response has silently returned null there.

- NormalizedCompanyRef now captures logo_path from both movie
  production_companies and series networks/production_companies.
- normalizer.company_logo_artwork() builds the single-image artwork
  entry for it (a company has exactly one logo ingested, so it's
  always is_primary) -- centralized there rather than duplicated in
  both ingestion modules, matching how movie/series artwork URLs are
  already built in one place.
- movie_ingestion.py and series_ingestion.py sync it via the same
  sync_artwork() the rest of section 10's self-hosting already uses,
  so it gets the same re-ingestion-safe upsert behavior for free.
- tasks.py cascades a download_artwork_task per referenced company
  after movie/series ingestion, same fan-out pattern as
  movie/series/season/person artwork.
