hive-c0re logs in with the hive's matrix sender token and creates the Space and rooms over swarm.matrix.apiUrl. On a hive that does not run the homeserver that crosses the network, so the default is now https://<gatewayHost>. hive-c0re already verifies against the hive trust bundle (SSL_CERT_FILE: system CAs, swarm root and the store's services root), which covers the gateway's leaf for that name. Also drops the remaining loopback-default wording in hive-c0re's matrix module and the openFirewall description, and pins the https default on a hive host without the homeserver in module-eval-matrix-core.
