Adds actual room-temperature capture for TRVs over MQTT and a background
Modbus poller for AC mode/fan/lock/room-temp, so the dashboard tile can show
real setpoint-vs-actual readings, an AC status block, and up to 3 radiator
icons per zone instead of just the setpoint.

Master switch should behave like each zone's own auto_mode — NewBook
polling, room-state tracking, and activity logging keep running as
normal; only the actual device setpoint commands are held back.

A single global toggle that overrides every zone's own auto_mode —
lets staff pause all HVAC automation stack-wide (e.g. during
maintenance) without touching each zone individually. Backed by the
existing config key/value store; pollOnce() short-circuits entirely
when off (no NewBook fetch, no state tracking, no device commands).

Manual on/off/mode/setpoint/fan control for MHI indoor units via the
already-verified Intesis Modbus TCP gateway, deliberately NOT wired into
the NewBook-driven scheduler yet — that stays deferred. Modbus doesn't
depend on the MQTT broker (separate infra, still unbuilt), so this can be
deployed and tested standalone.
- mhi_gateways table (connection config: host/port/slave id/address base)
+ zone_devices columns for MHI devices (gateway id, unit index, IU hint,
and the per-device register map staged from a MAPS import — ground
truth, never re-derived from room/IU at runtime)
- drivers/mhi-modbus.js: discover/getStatus/setTarget over modbus-serial,
same interface as trv.js/homeassistant.js; per-gateway request queue
since Modbus TCP requires serialised requests; falls back to the
profile's stride formula (with a loud warning) only if a unit has never
been through an import
- routes/mhi-gateways.js: gateway CRUD, live test-connection, xlsx import
(stages the parsed result for review — never auto-creates devices),
per-unit 'assign to zone' as the explicit commit step
- routes/override.js: GET .../mhi-status, POST .../mhi-control (control cap)
- frontend: GatewaysPanel (add gateway, test connection, import + preview,
assign units) and MhiControlPanel (on/off, mode, setpoint, fan) wired
into Devices.tsx / ZoneDetailModal.tsx

Ports the state machine, retry/backoff, and guest-override detection from
the retired homeassistant-newbook-heating-component, without depending on
Home Assistant. Backend (Fastify/pg) + frontend (React/Vite/TS) following
standard stack conventions; LXC 128 (127 was already taken by utilities).
MHI/Midea/Daikin/boiler drivers and the shared MQTT broker (LXC 104) are
later phases/infra, not included here.
