feat(doorman): unlock dispatch — arm switch + rest_command to doorctl [#345]

Founder-approved: valid badge + armed input_boolean -> rest_command
fires the pfvsvrpi doorctl endpoint (Tailscale-bound, token+source
allowlisted, self-securing relay). Disarm = boolean off = log-only.
URL secret on-box only (doorman_unlock_url).
