Ends the override leak: an SWO/PA save now applies to one device's line, not
every device the patient has. doc_status gains device_type ('' = legacy
patient-scoped row, applies until re-saved); the old unique key is dropped by
introspected name and replaced with the 4-col scope key. Staff overrides now
FEED THE VERDICT (device-scoped, staff wins over the CSV cell) instead of
display-only; visit overrides keep their patient-scoped fan-out via
confirmed_visits. PUT /api/doc-status and /api/confirm-visit accept an
optional echo of the patient's lines and return {lines, rollup_status}
recomputed through the same engine (stateless, no batch rebuild). Frontend
minimal fix: doc-status state and writes keyed patient:device. Independent
audit: SHIP (migration reproduced empirically on both old-key shapes; guard
scoped per its nit). 162 tests green.
