Replaces the ssh-keyscan-based known_hosts population (and the diagnostic step added to debug its flakiness) with two vars, GITEA_HOST_KEY and DEPLOY_HOST_KEY, each a full known_hosts-format line. No extra network calls before the real connections, no TOFU, and no more risk of tripping aquaria's connection-rate limiting — the actual root cause of the earlier flakiness was ssh-keyscan opening multiple near-simultaneous connections (one per probed key type).
