feat(jobs): step details quick-look modal for backend managers

Click a step's name in the embedded job-form list → opens a read-only
modal with everything a manager wants in one scroll: equipment,
schedule, master collect-measurements banner, operator instructions
(rich-text from recipe_node.description), measurement prompts list,
and values recorded so far.

Implementation: separate read-only form view bound to the embedded
field via context={'form_view_ref': '...'}. The standalone editable
form view stays registered for the Job Steps menu, so direct
navigation still loads the editable variant.

Three new computed/related fields on fp.job.step:
- quick_look_instructions (Html, related from recipe_node_id.description)
- quick_look_prompt_ids (filtered+sorted recipe_node.input_ids, step_input only)
- quick_look_recorded_value_ids (search across moves: input_value rows
  whose move.from_step_id == self.id)

Plus a small action_open_full_form method that escapes from the modal
to the editable form when the manager actually needs to edit.

Edge cases:
- No recipe_node_id → instructions panel shows empty-state hint
- collect_measurements=False → amber banner: "Master switch off — no
  values will be collected at runtime"
- Multiple moves on same step → values list shows all, newest first

Spec: docs/superpowers/specs/2026-04-30-step-details-modal-design.md.
Verified on entech: step "11. Hard Anodize Type III" populates with
516 chars instructions + 7 prompts.
