fix(plating): self-heal work orders missing recipe/steps + repair existing

Root cause: jobs auto-created at SO confirm resolve the recipe once; if the
SO line's process variant is not set at that instant (new parts, or the
copy-from-quote path), the WO is created with no recipe and no steps, and
setting the recipe on the line afterward never propagates (idempotency
guard + no line-to-job sync).

Fix (fusion_plating_jobs 19.0.12.6.0):
- fp.job._fp_resync_recipe_from_so(): re-resolve recipe from the SO line(s)
  and build steps (mirrors action_confirm: generate, promote pending to
  ready, express overrides). Acts only on not-started jobs; idempotent.
- action_fp_resync_recipe_from_so(): "Re-sync Recipe from SO" header button.
- sale.order.line.write: when x_fc_process_variant_id changes, auto-heal the
  linked not-yet-started WO.

Verified on entech: WO-30071-01/02 healed (recipe + 8 steps each); auto-
propagation confirmed in a rolled-back transaction. Deployed in place
(fusion_plating_jobs is ahead of git); same change recorded here.
