feat(promote-customer-spec): Phase D — reports + tablet payload include spec

Reports updated to print Specification (with revision via display_name):
- report_fp_sale.xml — header sections show "SPECIFICATION" instead
  of "COATING CONFIG", reads doc.x_fc_customer_spec_id (added on
  sale.order via quality inherit, computed from line.customer_spec_id)
- report_fp_wo_sticker.xml — propagates _spec alongside _coating
- fusion_plating_reports/report_fp_job_traveller.xml — header row
  now shows Specification (falls back to coating)
- fusion_plating_jobs/report_fp_job_traveller.xml — same fall-back
- fusion_plating_jobs/report_fp_job_sticker.xml — _spec added

sale.order.x_fc_customer_spec_id added as a stored compute on
sale.order (in quality) so reports can render order-level spec.
Mirrors the line's first spec; updates on line edit.

Tablet payload (shopfloor_controller.py):
- spec_label added to the job payload dict
- defensive 'customer_spec_id' in job._fields check (shopfloor doesn't
  depend on quality — circular if added)

Portal: deferred (same circular-dep issue, more substantial UI rewrite
needed; Phase E backlog item).
