feat(promote-customer-spec): Phase C — pricing, quality, job, cert re-keyed

Pricing:
- Quality inherit on fp.pricing.rule adds customer_spec_id + recipe_id
- Quality inherit on fp.quote.configurator adds customer_spec_id field
  + extends _find_matching_rule with priority chain:
    spec (+8) > recipe (+6) > coating (+4) > material (+2) > cert (+1)
- View inherit surfaces both new pickers on the rule form

Quality points:
- fp.quality.point now has customer_spec_ids + recipe_ids M2M filters
- Matcher (_matches + _find_matching) accepts new args
- Hook overrides on SO confirm + job confirm/done + step finish
  pass spec/recipe context through to the matcher
- View surfaces both new M2M widgets

Job:
- jobs/sale_order.py wires x_fc_customer_spec_id from SO line to
  fp.job.customer_spec_id on action_confirm

Cert:
- Quality inherit on fp.certificate adds customer_spec_id field +
  create() override auto-fills spec_reference from spec.code+revision
  Resolution priority: explicit spec_reference > cert.customer_spec_id
  > SO line spec (with print_on_cert) > legacy coating fallback
