feat(jobs): add lifecycle hooks — portal/QC/delivery/invoice (Tasks 2.6-2.9)

- Task 2.6: fp.job.action_confirm auto-creates fusion.plating.portal.job
  with x_fc_job_id back-reference. Idempotent (skip if already linked).
- Task 2.7: fp.job.action_confirm checks customer.x_fc_requires_qc
  and best-effort creates a fusion.plating.quality.check (the model
  lives in bridge_mrp; runtime-detected to avoid dep cycle).
- Task 2.8: fp.job.button_mark_done sets state='done', date_finished,
  auto-creates draft fusion.plating.delivery and best-effort triggers
  fp.certificate generation.
- Task 2.9: account.move.action_post links invoice -> fp.job via SO
  origin lookup, updates portal_job state to complete and stamps
  invoice_ref.

5 new tests cover: portal job creation + idempotency, mark_done state
+ delivery, cancel-then-mark-done blocked.

Best-effort patterns (try/except + runtime model detection) used for
QC + cert because their target models are in dependent modules
that this module doesn't depend on by design.

qc_check_id field on fp.job still deferred — adding it here would
require depending on bridge_mrp.

Manifest 19.0.1.4.0 -> 19.0.1.5.0.
