## Jira

- [SH-193](https://luby-us.atlassian.net/browse/SH-193)

## QA residual

- P0 done: technician is staged as a **local draft** until the vendor dialog is saved / wizard submitted — Cancel does not orphan a vendor row.

## Summary

- Adds **+ Add technician** to the WO board vendor dialog when a company context is known (from the row or the current selection).
- Stages a draft technician locally (`draft:` id) without calling `POST vendors` until the dialog save commits the selection.
- On save, create runs via the existing **`POST vendors`** REST endpoint (`vendorsApi.create` / `useCreateVendor`) using the company profile + new `contactName`.

## Backend

Uses the established vendor create API (`API_PATHS.rest.vendors` → `POST /vendors`). Each vendor record represents one technician; linking to an existing company is done by sending the same `companyName` (and optional `companyId` when available). **No new endpoint**.

## Test plan

- [ ] Open vendor dialog → **+ Add technician** → fill name → Cancel dialog → no vendor create API call.
- [ ] Add technician → Save dialog → `POST /vendors` once; row shows new tech.
- [ ] `npm run verify`

## Out of scope

- Multi-POC, multi-tech arrays on WO, vendors directory redesign.
