feat(fusion_plating): kind.area_kind drives Shop Floor column routing

Add required area_kind Selection to fp.step.kind so each kind
self-declares which plant-view column its steps belong in. Replaces
the hardcoded _STEP_KIND_TO_AREA dict (removed in fp_job_step.py
in the follow-up commit).

- New `blast` kind for the Blasting column (sequence=35)
- 26 existing kind records seeded with area_kind in XML
- Pre-migrate 19.0.21.2.0 seeds existing rows BEFORE NOT NULL hits
  the schema; also activates derack/demask/gating that were
  deactivated in 19.0.20.6.0 but are needed for the full taxonomy
- Step Kind form + list views surface area_kind (badge + chip)
- Step Kind search adds Group By Shop Floor Column
- Simple Editor kind picker shows "Masking — Masking column"
  suffix so authors see the routing at pick time
- Add Hot Water Porosity Test (A-15) + Final Inspection / Packaging
  templates (used by 7+3 recipe nodes that previously had no
  library entry)

+"""19.0.21.2.0 — Shop Floor live-step + kind taxonomy.
+
+Seeds fp.step.kind.area_kind on existing kinds BEFORE the required
+NOT NULL constraint on the new field hits the schema. Also activates
+the three kinds (derack/demask/gating) that were deactivated in
+19.0.20.6.0 but are needed for the full area_kind taxonomy.
+
+Idempotent: only fills NULL / inactive rows.
