feat(plating-menu): Layer 1+2 — explicit groups on top-level menus + submenus

Phase D Tasks D1-D4 of permissions overhaul. Adds explicit groups=
attributes to:
- 9 top-level Plating menus (matrix per spec Section 2.E)
- Quality submenus: Audits, Customer Specs, AVL → QM-only
- Compliance hub child submenus (CGP, General, Safety, Aerospace,
  Nuclear) → QM-only
- Operations submenus: Maintenance, Move Log, Labor History → Shop
  Manager+; Replenishment Suggestions → Manager+

Replaces fragile inheritance + action-ACL-based visibility with
explicit per-menu gates. Now every role's menu tree is deterministic.

Also adds fusion_plating/tests/test_menu_visibility.py — per-role
matrix tests using ir.ui.menu.search_count with the test user.
