fix: clear CodeQL weak sensitive hashing on model catalog cache key

SHA-256 of API key material in _cache_key trips
py/weak-sensitive-data-hashing (CodeQL alert #64). Use HMAC-SHA256 with
the credential as the key and a fixed app message so the cache partition
id stays non-reversible without password-style hashing.
