feat(plating): Sub 5 — order-line fields (serial, job#, thickness, revision)

Four new fields on every sale.order.line, propagated through to MO,
Delivery, and Invoice for end-to-end traceability:

- fp.serial registry (new model in configurator) with smart-button
  traceability to Sale Order, MO, Delivery, Invoice, Part. M2O on SO
  line; optional; user types a customer serial or clicks Generate
  Serial for a sequence-backed one. Reverse O2M links split across
  configurator (invoice) / bridge_mrp (MO) / logistics (delivery) so
  module load order is respected.
- x_fc_job_number on SO line, auto-sequenced FP-JOB-NNNNN on SO
  confirm. Editable — shops can override for customer/legacy schemes.
- fp.coating.thickness (new child of fp.coating.config) with per-
  config discrete thickness options; x_fc_thickness_id on SO line
  domain-filtered to the line's coating. Auto-clears when coating
  changes.
- x_fc_revision_snapshot Char on SO line, frozen from
  x_fc_part_catalog_id.revision at save. Protects historical SOs from
  later catalog edits. Secondary "Revision" picker on the tree view
  lets users switch between prior revisions of the same part number;
  the Part M2O still surfaces only is_latest_revision rows.

Reports (CoC, packing slip, invoice, BoL) pick up all four via the
Sub 2 customer_line_header macro — one macro edit, four reports.

Smoke on entech: 11 assertions pass including revision snapshot,
generate-serial button, typed-serial create-on-fly, coating→thickness
domain reset, SO confirm auto job#, and MO traceability carry.

Module version bumps:
  fusion_plating_configurator  → 19.0.12.0.0
  fusion_plating_bridge_mrp    → 19.0.11.0.0
  fusion_plating_logistics     → 19.0.2.0.0 (+depends configurator)
  fusion_plating_reports       → 19.0.5.1.0
