Add Ansible playbooks for MeshCore monitoring node deployment

Roles: base (apt, tailscale, motd), meshcore_cli (pipx), meshcore_capture
(agessaman/meshcore-packet-capture + .env.local template), scripts (voltage, bandwidth).

Host vars contain per-device serial ports; group vars hold shared MQTT broker config.
