refactor(menus): collapse separate Jobs submenu into Shop Floor

Move 'All Jobs' and 'Steps' under fusion_plating_shopfloor's
existing 'Shop Floor' submenu (between Tablet Station and Bake
Windows). The standalone 'Jobs' parent menu is gone — it was
redundant once the operator UIs (Plant Overview / Tablet /
Manager Desk) consolidated under Shop Floor.

Final structure under Plating:
  Sales / *
  Configurator / *
  Shop Floor
    Manager Desk
    Plant Overview
    Tablet Station
    All Jobs       ← moved here (seq 15)
    Steps          ← moved here (seq 17, supervisor+)
    Bake Windows
    First-Piece Gates
  Receiving & Inspection
  Operations / *
  Configuration → Work Centres (manager)
  ...rest

Work Centres stays under Configuration (no shopfloor equivalent).

New menu file lives in fusion_plating_jobs/views (jobs depends on
shopfloor; core can't reference shopfloor xmlids).
