Same pattern as plant_kanban — workspace payload denormalizes
cross-module fields Technician can't read directly (sale.order,
fp.part.catalog, customer_spec, etc.). job.sudo() at the top so
the whole render path is sudo'd.
Job Workspace was stuck on 'Loading...' with a server-error toast
because the route returned {ok:false, error:'...'} (27-byte response)
when the first cross-module field access AccessError'd.
