feat(jellyseer): move jellyseerr_api_key to an encrypted secret (slice 2/3)

The Jellyseerr API key was stored as plaintext in the Jellyfin service config.
It is now a SecretField on the Jellyfin service, so it is encrypted at rest and
rendered as a masked secret input (the generic config editor stops exposing
it, and the secret editor picks it up automatically).

Migration (idempotent, runs in ensure_defaults):
- _migrate_jellyseerr_api_key_to_secret: for every Jellyfin service with a
  plaintext jellyseerr_api_key still in config, encrypt it ONCE into the
  secrets blob (direct UPDATE so existing encrypted secrets are preserved, not
  re-encrypted) and remove it from config.
- _migrate_jellyseerr_into_jellyfin: standalone-jellyseerr absorption now
  stores the key as a secret, and decrypts the Jellyfin api_key before handing
  it to upsert_service (fixes a pre-existing double-encrypt on that rare path).

The stats provider already reads jellyseerr_api_key from secrets-or-config, so
it works before, during, and after the migration.

Tests: absorbed-key lands in secrets (and existing api_key isn't corrupted);
new plaintext-config -> secret migration + idempotency. 401/401 backend pass.
