Dingtian relay driver — resolves the ticket-first entry blocker

Browse Source 
The Dingtian board's inputs are independent of its relays (configurable), so a
button on an input can report to the host WITHOUT auto-firing a relay — solving
the access-controller-button-flow blocker the UHPPOTE/ZKTeco couldn't.

packages/devices:
- access-dingtian.ts: `dingtian` access driver implementing AccessControlDevice
  (relay pulse/latch via UDP string protocol :60001), InputDevice (read inputs +
  poll-based press/release events, active-LOW), and the new PreconditionDevice.
- PreconditionDevice capability on the interface: a device can report config it
  requires for parking and optionally fix it. Dingtian checks input_link_relay
  via the HTTP config API and can disable it.
- httpPort config field — the web/config API port is separate from UDP control
  (this unit uses 8080, not the default 80).
- Register dingtian; export driver objects from the package.

Verified on real hardware (DT-R004 @ 10.0.10.172): status read, relay pulse,
input events; disabled input_link_relay via the driver, then confirmed pressing
inputs fires NO relay (0000) — host-in-the-loop entry works.

Config-write gotcha recorded: config_set.cgi requires "command":"setconfig"
injected after "status" (GET omits it) or the POST silently no-ops.

apps/server/scripts/dingtian-test.mjs: status / watch / pulse hardware test.
wiki: dingtian-relay verified; button-flow marked RESOLVED; index + log.

## Decisions
- [[standing-decisions]] — settled decisions (stack, platform, integrity, access control, readers).
- [[open-questions]] — 7 open items (6 procurement + JWT key choice); ESP32 device auth deferred.
- [[access-controller-button-flow]] — ⚠️ BLOCKER: UHPPOTE/ZKTeco on hand can't do ticket-first entry as wired.
- [[access-controller-button-flow]] — ✅ RESOLVED: Dingtian decoupled inputs enable ticket-first entry (was a UHPPOTE/ZKTeco blocker).
- [[autonomous-direction]] — roadmap: toward fully unmanned (no booth); reshapes threat model + fail-state.
- [[dingtian-vs-mqtt]] — transport choice: direct HTTP/UDP now, MQTT parked until multi-lane scale.
