Custom data (workstation)

A block of JSON attached to this workstation that the MRP validates, stores, shows, and otherwise never interprets. It is for integrations: where the G-code for a printed part lives, a printer profile, a link to assembly instructions, a filament's density.

Planners edit it in the box; a parse error names the position. Integrations read and replace it with GET / PUT /api/workstations/{id}/custom — the body is the JSON itself, no envelope (see the API).

Workstations and work orders have the same page.
