julian 7fd407ac82 Harden Dingtian: authenticated binary relay + disable unused channels
Lock down the relay device for the flat (no-VLAN) network.

Relay control:
- pulseOpen/setRelay now use the Dingtian BINARY protocol (:60000) with a
  relay password — the only relay option with auth (string :60001 has none, and
  is kept only for the read-only status query). Frame verified on hardware.

HardenableDevice capability (driver harden()):
- set a random relay_pw (1-9999); disable unused channels (rs485/can/tcp x2/mqtt
  -> p:255), keeping UDP1 binary (control) + UDP2 string (status).
- write-verified (device reboots on apply).

Assign/Save flow now does: fix preconditions -> harden -> set up input push;
the relay password is stored in lane_devices so the runtime device can command
the relay.

DELIBERATELY NOT touching the device's HTTP CGI session check (session_en):
enabling it on this firmware breaks the config-READ API (ECONNRESET) and locked
the backend out — required a factory reset to recover. The open CGI API is
accepted as flat-network reality; the signed event log is the real guarantee.

Verified end to end on hardware: assign hardens + configures the device, config
API stays reachable, pulseOpen with the stored password fires the relay, without
it is rejected. wiki: device-input-flow + dingtian-relay updated.
