Cover-fetch overhaul (#30)

Fixes the silent "No Result(s) found!" UX for English-language metadata
searches. Live diagnosis on the v4.0.8 instance for Animal Farm george orwell
returned zero candidates from any provider; this release brings that to
82 candidates across 9 providers.

What's new

• Open Library as a first-class metadata provider — free, no key, auto-registers.
• Google Books API key support (config_google_books_api_key) — lifts the
  per-IP anonymous quota of 1k req/day. Free key at console.cloud.google.com.
  Configure under Admin → Configuration → Feature Configuration.
• Per-provider status in /metadata/search — modal now shows a one-line
  status per provider (✓ 10 results, ⏱ rate limited, 🔒 missing key,
  ⛔ blocked (Amazon 503)) with duration_ms.
• In-modal API Keys panel — "🔒 API Keys" toggle next to provider list.
  Admins can paste a Hardcover / Google Books / Goodreads key and save without
  leaving the Fetch Metadata dialog.
• CWA_METADATA_DEBUG=1 env knob — bumps every metadata-provider logger
  to DEBUG without touching the global level.

Upgrade

docker compose pull && docker compose up -d

DB migration is automatic (column auto-add path in cps/config_sql.py).

Out of scope (deliberately deferred)

• Goodreads API (discontinued in 2020 by Amazon).
• DNB cover SSL-EOF errors and a NoneType.language parse bug — separate
  follow-up PR.
