fix(plating): single bilingual CoC — remove the separate French print action

The CoC body now renders English + the French translation together, so the
separate "Certificat de Conformité (Français)" print option was redundant.

- Removed the action_report_coc_fr report action and the now-dead
  report_coc_fr template; renamed action_report_coc_en to "Certificate of
  Conformance" (print filename "CoC - <name>").
- fp_notification_template: dropped the per-partner-language EN/FR branch —
  CoC email attachments always render the single bilingual action_report_coc_en.
- fp_hide_default_reports: dropped the FR sequence record.
- Refreshed the report_coc.xml design note.
- Bump reports 19.0.11.32.0, notifications 19.0.7.1.0.

Deployed on entech (-u removed the orphan FR action + template). Verified the
cert Print menu now lists only "Certificate of Conformance" and it renders
clean. The dead action_report_coc_fr ref in the uninstalled
fusion_plating_bridge_mrp is left as-is (module not loaded).
