feat(jobs+certs): milestone-cascade Phase 1 + session patch catch-up

Implements the milestone-cascade design (Phase 1) and catches the
fusion_plating_jobs / fusion_plating_certificates source up to entech.

Milestone cascade (this PR's core):
- fp.job: new computes all_steps_terminal, next_milestone_action,
  next_milestone_label; dispatcher action_advance_next_milestone with
  3 helpers (_action_open_draft_certs, _action_open_draft_delivery,
  _action_mark_active_delivery_delivered); _resolve_required_cert_types
  resolver; _fp_create_certificates rewritten to honour
  part.certificate_requirement + partner flags + loop over resolved
  cert types
- fp.job.workflow.state: new trigger_on_delivery_state Boolean;
  _fp_is_passed_for_job extended with delivery-state branch;
  Shipped state seed reroutes from default_kind=ship to the new trigger
- View: hide Finish & Next when all_steps_terminal; add 4 mutually-
  exclusive milestone buttons (Mark Job Done / Issue Certs / Schedule
  Delivery / Mark Shipped) bound to one dispatcher
- Cert gate (fusion_plating_certificates/models/fp_delivery.py):
  action_mark_delivered hard-blocks on draft certs; manager bypass
  via fp_skip_cert_gate=True context key
- 24 unit tests in test_fp_job_milestone_cascade.py covering computes,
  resolver, dispatcher, cert gate
- Spec: docs/superpowers/specs/2026-05-12-job-milestone-cascade-design.md
- Plan: docs/superpowers/plans/2026-05-12-job-milestone-cascade.md

Other entech changes caught up in this sync (from earlier session
patches not previously committed):
- fp.job version bump series 18.x → 19.0
- res_users_views.xml addition (signature widget in user prefs)
- racking inspection smart button removal
- various view/manifest touch-ups
