move the hive's vhosts and matrix discovery out of the gateway
The dashboard vhost, the hive domain vhost and the dashboard's local name move to hive-c0re/vhosts.nix; the matrix .well-known discovery and the legacy /matrix/ redirect move to glue-matrix-hive-discovery.nix, which adds them to the hive domain vhost. Both declare through gateway.vhosts. hive-gateway/vhosts.nix keeps the catch-all only, and the gateway no longer reads deploy.matrix or c0re.servedFrontend, nor deploy.hive-controller.enable for its vhosts. Part of #3742.
