feat(jobs): Phase 6 lean — scan controller + process-tree JSON endpoint

Phase 6 originally scoped the full operator UI rewrite (Plant
Overview, Tablet, Manager Dashboard, Process Tree). Tailscale SSH
to entech is currently unavailable, so live in-browser
verification of OWL/JS components isn't possible. Shipping a lean
Phase 6 with the data-layer pieces:

1. /fp/job/<id> scan controller — when a user scans a fp.job
   sticker, lands them on the fp.job form (or the process tree
   action once that's wired). Mirrors fusion_plating_reports' /fp/wo/
   pattern.

2. /fp/jobs/process_tree JSON endpoint — returns the recipe tree
   serialized with each node tagged by its fp.job.step state,
   ready for an OWL component to render. The component itself is
   deferred (see README.md).

The bigger UI deferrals (kanban, tablet, manager dashboard) are
documented in README.md. They get their own focused project after
cutover — the data layer is complete, so they can land
incrementally without touching fp.job/fp.job.step.

Tests verify controller imports + serialization shape (no HTTP
because TransactionCase doesn't easily simulate request context).

Manifest 19.0.1.8.0 → 19.0.1.9.0.
