chore: session housekeeping — tank UX, plating menu defaults, WO label

- fusion_plating: tank field labels (Code → Tank Number, Tank → Tank Name)
  + state-control header buttons (Mark Empty/Filled/In Use/Draining/
  Maintenance/Out of Service) with chatter audit logging.
- fusion_plating_configurator: Plating app default landing screen = Sale
  Orders, while keeping menu name as 'Plating'.
- fusion_plating_jobs: SO smart-button label 'Plating Jobs' → 'WO'.

Already deployed and verified on entech earlier in the session.
