Ports fusion_plating_shopfloor's process_tree.js to bind to fp.job
instead of mrp.production. Consumes the /fp/jobs/process_tree
JSON endpoint built in Phase 6 lean.
Renders the recipe tree as cards. Each operation card shows the
step state (pending/ready/in_progress/done/etc.) when there's a
matching fp.job.step. Click an operation card -> open the step
form. Click Back -> return to the job form.
New 'Process Tree' button on the fp.job form (manager-only)
launches the client action with job_id context.
Manifest 19.0.2.1.0 -> 19.0.2.2.0.
