DEPLOYED parts live on a host; every other state lives in a bin (or
unassigned). Previously binId and hostId were independent nullable
fields with no validation, so the Edit Part dialog could leave a
DEPLOYED part with only a bin and no host — which silently dropped
it from the repair problem-part picker.
- Service: resolveLocation() helper enforces the invariant on create
and update. On a state transition, update auto-clears the stale
relation and emits LOCATION_CHANGED for the cleared side.
- Zod: CreatePartRequest.superRefine rejects mismatched state/location
up front; UpdatePartRequest rejects both-fields-set.
- Web: PartFormDialog swaps a single Location field between Host
combobox (DEPLOYED) and Bin combobox (others); switching State
clears the opposite field. Parts list + detail render host first,
then bin path, then Unassigned.
- Tests: 9 new cases covering the invariant including the no-op guard
so an unrelated PATCH on a DEPLOYED part doesn't touch hostId/binId.
