feat(jobs+receiving): confirm->receive flow, lock recipe, reset step, lock steps, fix bake gate

- Confirm->Receive (A): after a single interactive SO confirm, receiving's
  action_confirm returns action_view_receiving() so the user lands straight
  on the Receive Parts screen (opt-out via fp_no_receiving_redirect context).
- Lock recipe (1): recipe_id readonly on the WO form — stick to the
  order-entry recipe.
- Hide spec (2): customer_spec_id invisible on the WO form.
- Reset step (3): new fp.job.step.button_reset (operator-usable, audited) +
  an undo button next to Start. Resets to Ready, clears finish + sign-off,
  closes open timelogs, keeps start audit + move/CoC history.
- Lock steps (4): steps list create=false delete=false (no Add a line / no
  trash) — steps come from the recipe, only skippable, never deleted.
- Bake gate fix (5): _fp_missing_required_step_inputs now honours the node's
  collect_measurements master switch, matching the Record-Inputs wizard.
  collect_measurements=False + required prompts no longer blocks finish
  (wizard shows 0 rows, so the gate must too). Unblocks WO-30098 + 63 other
  affected nodes (bake steps).

Deployed + verified on entech (-u jobs; bake finishes, reset done->ready,
recipe readonly, spec hidden, steps locked, receiving redirect target OK).
