fix(auth): dev login 403 — resolve staff by id, not oidcSub (GRO-150)

The DevLoginSelector stores the staff database id in localStorage and
sends it as X-Dev-User-Id. The resolveStaffMiddleware incorrectly
looked up staff by oidcSub instead of id, causing all API endpoints
to return 403 for every user in dev mode.
