feat(promote-customer-spec): Phase E — final removal of coating + treatment

DELETED entirely (model + view + ACL + data file + menu):
- fp.coating.config (configurator)
- fp.treatment (configurator + seeded data)
- fp.coating.thickness (configurator) — replaced by fp.recipe.thickness in Phase A
- fp.customer.price.list (configurator) — coating-keyed, no replacement

Field deletions:
- sale.order.x_fc_coating_config_id
- sale.order.line.x_fc_coating_config_id + x_fc_treatment_ids
- account.move.line.x_fc_coating_config_id
- fp.part.catalog.x_fc_default_coating_config_id + x_fc_default_treatment_ids
- fp.job.coating_config_id
- fp.pricing.rule.coating_config_id
- fp.quality.point.coating_config_ids
- fp.direct.order.line.coating_config_id + treatment_ids
- fp.sale.description.template.coating_config_id

Refactored:
- fp.quote.configurator.coating_config_id → recipe_id (now points at
  fusion.plating.process.node, the actual recipe). All compute, onchange,
  and matcher logic updated to use recipe directly. Quality inherit
  extends matcher with spec-tier scoring.
- fp.job._fp_create_certificates now reads spec from job.customer_spec_id
  and formats spec_reference as "code Rev rev". Same for thickness
  source — bake fields read from recipe_root (Phase A).
- fp.job.step.button_finish bake-window auto-spawn reads bake settings
  from recipe_root instead of coating.
- fp.certificate auto-fill spec_min_mils/max_mils from recipe (Phase A
  thickness fields) instead of coating.
- jobs/sale_order.py: job creation reads x_fc_customer_spec_id from
  line, drops coating refs and the legacy header-coating fallback.
- Wizards drop coating + treatment fields and refs.
- Configurator views drop x_fc_coating_config_id + x_fc_treatment_ids
  fields entirely. Quality inherits re-anchor on stable fields
  (x_fc_part_catalog_id, x_fc_internal_description, default_process_id,
  process_variant_id, substrate_material) so they keep working.
- Reports drop coating fallback elifs; print recipe / spec.
- Tablet payload drops coating_config_id from job.read fields.

Skipped (deferred to backlog):
- fusion_plating_bridge_mrp — module is uninstalled per Sub 11; source
  files retain coating refs but no runtime impact.
- fusion_plating_portal — circular dep (portal → quality → certs →
  portal). Customer-facing portal coating picker stays for now;
  promote-spec polish is a separate sub-project.

Verification: grep for "coating_config_id|fp.coating.config|
fp.treatment|fp.coating.thickness" in live (non-bridge_mrp,
non-portal, non-script, non-test) Python/XML/CSV returns 3 hits,
all in module / class docstrings explaining Phase E history.
