Check if a user is blocked GET
Definitive blocked-state lookup for a single contact. Meta exposes no membership endpoint, so this reads Zernio's blocklist mirror (kept in sync by the block/unblock endpoints; the first call per account backfills the mirror from Meta's full list). Constant-time regardless of blocklist size.
