Completes the split: `nodes` now holds only how a device is drawn on one
canvas, and every device fact reaches the API from the inventory row.
- The device columns are removed from `nodes` (SQLite table rebuild, the
same shape as the existing device_inventory and canvas_state rebuilds).
The drop is skipped, and logged, while any non-furniture node is still
unlinked: those columns are the last copy of that node's facts. The
backfill therefore reads them with raw SQL — by the time it runs, the
model no longer declares them.
- The status checker iterates devices, not nodes: one check per device
however many canvases draw it, writing `status_live` / `last_seen` /
`response_time_ms` on the row. `/ws/status` messages carry `device_id`
and the node ids they light up. Hidden devices are not probed.
- Readers repointed: scanner (last_scan lands on the row), proxmox (its
node tier collapses into the inventory tier, keeping only the cluster
handles), zigbee/zwave (one property refresh serves every canvas), rack
inventory, liveview, stats, node dedupe.
- `POST /scan/pending` merges into the row that already describes the host
instead of minting a second one — one device is one row, whichever way it
was documented.
- Standalone keeps parity: the canvas blob gains `devices`, split on save
and hydrated on load. A blob written before the split still reads.
The rack inventory had a related bug: a mount that names a node explicitly
printed the mount's device rather than the pinned node's. It now reads the
node's own row.
Tests that built a node with device columns are ported to the link; where a
behaviour genuinely moved (properties refresh once on the row, last_scan is
the device's) the assertion moved with it rather than being dropped.

Autosave saves whenever hasUnsavedChanges is set, so any source that
dirties the canvas without a user edit turns into a spurious silent
save. Two such sources:
1. Live status updates. useStatusPolling routed backend status pushes
through updateNode, which always sets hasUnsavedChanges. With the
60s status cycle, an idle opted-in tab saved itself every cycle and
could clobber edits made elsewhere with its stale in-memory canvas.
Add setNodeStatus, a live-overlay action that updates a node's
status/response_time/last_seen without dirtying (mirrors
setServiceStatuses), and route polling through it.
2. Initial dimensions measure. onNodesChange treated React Flow's
first-measure `dimensions` change as an edit, marking a freshly
loaded canvas dirty before any interaction — autosave then saved on
every load/switch. Only count a `dimensions` change as an edit when
it is a real resize (resizing === true).
Add regression tests: setNodeStatus updates status without dirtying;
onNodesChange ignores initial-measure dimensions and select-only
changes but still dirties on a user resize.

Adds optional live status checking per service (not just per node),
requested as a follow-up to issue #196.
Backend:
- New check_service / check_services: HTTP(S) GET for web services, TCP
connect otherwise; UDP and port-less non-web services stay 'unknown'.
- New scheduler job 'service_checks', independent interval (default 300s),
added/removed live via set_service_checks_enabled.
- Settings gain service_check_enabled + service_check_interval (>=30s),
persisted to scan_config.json. New WS message type 'service_status'.
Frontend:
- Live per-service status overlay in canvasStore (not persisted, so it
never round-trips through canvas save), fed by the WS message.
- DetailPanel + canvas node service rows: offline service turns red
(#f85149), otherwise keeps its category colour.
- SettingsModal: toggle + interval input (default 300s / 5 min).
Off by default — no behaviour change until enabled.
