Add rig_ports map to RigctlFrontendConfig. When non-empty, one rigctl
TCP listener is spawned per entry instead of the single shared listener,
each routing commands to its assigned rig via rig_id_override on RigRequest.
Add rig_id_override: Option<String> to RigRequest so the remote client
can route individual requests to a specific rig without changing the
globally selected rig. build_envelope prefers the override when set.
Example config:
[frontends.rigctl]
enabled = true
listen = "127.0.0.1"
port = 4532
rig_ports.ft817 = 4532
rig_ports.airspyhf = 4533
