refactor(setup): unify controller I/O — event-driven relays[] + generic inputs[]

The controller new/edit modal hardcoded both its outputs and its inputs, so an
operator could neither add a generic event-driven relay nor a free-standing input
(e.g. a second radar at the exit). This unifies both into symmetric, first-class
lists. Behaviour for existing booths is unchanged (back-compat, no DB migration).

Outputs — one event→action relays[] list:
- A relay is "when EVENT X happens, do its action": entry/exit/both pulse a
  barrier; a new `radarAlert` event drives a non-barrier alert lamp (blink while
  its trigger input is active, SOLID once the camera confirms a car).
- Dropped the separate config.buttonLight block — the lamp is just a relays[] row
  with direction:"radarAlert" (triggerInput + blink cadence). `alertRelaysOf()`
  replaces `buttonLightOf()`; ButtonLightController keeps its proven 3-state
  machine (serialized UDP, fail-OFF, hot-reload), now keyed per controllerId:relay
  so several alert lamps on one controller run independently. Every barrier
  resolver skips radarAlert rows (no auto-open; barrier-not-a-door intact).

Inputs — one first-class config.inputs[] list (the twin of relays[]):
- Each row is { input, role, relay?, kind?, activeLow?, cooldownSec? } with a
  "+ Add input" button. role ∈ button | presence | alertTrigger; button/presence
  name the relay they serve. An exit radar is just another presence row.
- Keystone `inputsOf(row)`: returns config.inputs[] or SYNTHESIZES it from the
  legacy relays[].button/presenceInput/... fields, so relayForButton /
  relayForPresence resolve identically from either shape — zero-downtime, no
  migration. entry-flow.ts is unchanged (resolves through the same functions).
- Fixed a latent bug this exposed: the alert lamp's camera lock was hardcoded to
  the ENTRY camera. Added relays[].lockLane ("entry"|"exit", default entry); the
  lamp now locks on its own lane's camera, so an exit radar's lamp tracks the exit
  camera. button-light tracks both #entryBusy/#exitBusy.
- Driver: extracted activeLowFrom(config) — merges inputs[] activeLow, legacy
  relays[].presenceActiveLow, and the inputActiveLow escape hatch.

UI: the relay dropdown gained a "Radar alert" option (reveals trigger/lock/blink
inputs); InputEditor is rewritten to a generic list (role select folds loop/radar);
i18n sq+en kept at type-parity.

Tests: new device-resolve.test.ts (inputs[] resolution + legacy fallback identical
+ exit-radar resolves to the exit relay); button-light gains a two-independent-
alert-relays case and an exit-lamp lockLane case; access-dingtian gains
activeLowFrom cases. Full workspace build/lint/test green (i18n parity included).

Wiki + memory updated (button-light-indicator, entry-double-press, dingtian-relay).
