openhop/repeater: add MeshCore repeater role

Deploys the openHop MeshCore repeater on a Raspberry Pi with a RAK6421
WisMesh Pi HAT: installs the daemon into a venv from a versioned git tag,
templates config.yaml and a systemd unit, and loads board pin maps and RF
region presets by name from vars/. identity_file is configurable and
defaults to null (daemon generates its own keypair).
