ansible: move the cross-host ports to host_vars, delete services_config.yml The four ports were the only entries in services_config.yml with a real justification: each is read twice, by the role that deploys the service on its own box AND by a socket-proxy or Caddy play that runs on the EDGE host and publishes it. A role default is invisible to that second play. But the shape was wrong in two ways. The file had to be named in vars_files: by 30 plays - opt-in configuration that someone will eventually forget - and five role defaults silently interpolated service_settings., so bitcoin_knots, fulcrum, datum_gateway and mempool were not self-contained: using any of them without that one vars_file entry broke it. Each port now lives in host_vars/<owning box>/main.yml: host_vars/knots_box_local/main.yml bitcoin_p2p_port, datum_gateway_api_port, datum_gateway_stratum_port host_vars/fulcrum_box_local/main.yml fulcrum_ssl_port host_vars/mempool_box_local/main.yml mempool_frontend_port host_vars auto-loads and outranks role defaults, so the owning role picks the value up with no vars_files at all, and the edge play reads the same single definition as hostvars['<host>'].<name>. The role defaults keep the protocol standard (8333, 50002, ...) so each role still works standalone, with the live deployment's value in host_vars winning. Also fixed a fourth copy of an inventory identity: the mempool Caddy play had "mempool-box:{{ ... }}" hardcoded in the upstream. It now derives the host from hostvars['mempool_box_local'].ansible_host, so inventory is the only place any box's name is written down. services_config.yml is deleted, with 25 more vars_files entries across 19 playbooks. Between this and the previous commit, 87 vars_files entries are gone and every variable in the repo now comes from group_vars/all, host_vars, inventory, a role default, or that service's own _vars.yml. Verification: an edge-host probe resolves all eight ports and hostnames to byte-identical values to the ones services_config.yml used to supply. Each owning host resolves its own port through host_vars. All 37 playbooks' --list-tasks output is unchanged. The four edge plays that consume these values all check-diff changed=0 - the socket-proxy and Caddy units on vipy are byte-identical, which is the direct proof the rewiring landed on the same values. fulcrum and datum-gateway check-diff exactly as before (ok=28/changed=1 and ok=15/changed=1, both the known timer re-arm).
