refactor(reports): move SO Acknowledgement into fusion_plating_reports with house style

D7 template was originally in fusion_plating_configurator with a
Bootstrap-only look-and-feel that didn't match the other Fusion
Plating reports. Re-styled and relocated:

- Moved to fusion_plating_reports/report/report_fp_so_acknowledgement.xml
  alongside sale / work-order / job-traveller / invoice templates.
- Uses fp_portrait_styles (company primary colour for headers, .bordered
  tables, .info-header row, .totals-table, .highlight-box, .sig-box /
  .sig-line / .small-muted).
- Layout now mirrors report_fp_sale.xml: Billing / Shipping address
  pair, references row (Customer PO / Customer Job / Order Date /
  Salesperson), scheduling row (Planned Start / Internal / Customer
  Deadline / Ship Via), blanket-order callout, order line table
  (PART / DESCRIPTION / TREATMENT / QTY / UNIT PRICE / SUBTOTAL),
  totals table with subtotal / taxes / grand total, and a two-column
  signature block.

fusion_plating_configurator no longer ships report/ files — it
depends on fusion_plating_reports transitively via installed modules
order. Report XML ID changed from
'fusion_plating_configurator.report_fp_so_acknowledgement_doc' to
'fusion_plating_reports.report_fp_so_acknowledgement_doc'.

UAT on S00066: PDF renders cleanly with ENTECH branding, contact
footer, subtotal \$3,025 / taxes \$393.25 / grand total \$3,418.25,
signature lines — visually identical to the Quotation/Sales Order
report.
