The rack's link picker read `/nodes`, so it only ever offered devices
someone had already approved onto a logical canvas — two rows on a homelab
holding 74 inventory entries. A device on no canvas is still the record of
a real box, and is exactly what a rack is built out of.
`DevicePickerModal` replaces `NodePickerModal` and lists the Device
Inventory itself. Picking an entry calls the new `relinkDevice`, which
repoints the mount's `deviceId`, adopts that entry's node, status and —
unless the user renamed the plate — its label. One entry, one mount: a row
another plate stands for is not offered, and the store refuses it anyway.
The placeholder a rack-created plate left behind is dropped through the new
`DELETE /api/v1/scan/pending/{id}`, which refuses a device a rack still
mounts (409): foreign keys are off at runtime, so the mount would be left
naming a row that no longer exists.
`LinkedDevicePanel` becomes "Linked device" and now prints what discovery
found even when nothing on a canvas answers for the device; only the
canvas-side rows go missing, under a "Not on a logical canvas." note.
Also renames `pending_devices` to `device_inventory` (and
`pending_device_links` to `device_inventory_links`), with the Python and
TypeScript names that followed it. "Pending devices" was the scanner's word
for a queue of finds awaiting approval; the rows outlive approval, are
edited by hand and are what a rack mounts. Routes, payload keys and MCP
tool names are a published contract and are unchanged — `/scan/pending/*`
and the `pending_devices` key in `/stats` stay as they are.
The rename migration runs before `create_all`, or an empty new table would
be created beside the populated old one and every scanned device would read
as gone; it repairs that state too, for anyone whose app already started
mid-upgrade. Foreign keys are switched on for the rename so SQLite rewrites
the `REFERENCES` clause in `rack_devices`.
