fix(operator-wizard): surface office-authored instructions to operators

Critical UX gap discovered in production-environment battle test: when
operator hits "Mark Done" and the input wizard fires, they only saw the
measurement prompts list. The rich-text instructions written by the
office (recipe_node.description) never reached the operator at the
exact moment they need them.

Fixed: wizard model gains instructions (Html, computed from
step.recipe_node_id.description) + has_instructions flag.
Form view renders the instructions in a prominent blue alert at the
top of the wizard, above the Measurements list. Hidden when blank
so operators on instruction-less steps don't see noise.

Also: extend default_kind Selection on fusion.plating.process.node to
match fp.step.template — both models now have the same 24 kinds. Without
this, recipe authors could pick a kind in the library template form
that the recipe-node Selection rejected with a ValueError.

Battle test artifact:
- Recipe "Hard Anodize Type III + Dye + Seal" (id=1863) — 23 steps,
  105 measurement prompts, rich-text operator instructions per step
- SO S00278 for ABC Manufactoring confirmed → fp.job 1236 / WH/JOB/00337
  with all 23 steps materialized, 105 prompts visible to operators
- Wizard test: step "11. Hard Anodize Type III" → 516 chars of
  instructions render + 7 input prompts in the form
