[CLAUDE] Phase1.2: CRUD Master + Permission Matrix + FE admin pages

Backend:
- Domain/Master: Supplier (+ SupplierType 5 loai), Project, Department (AuditableEntity)
- Domain/Identity: MenuItem, Permission, MenuKeys const (12 menu)
- EF Configurations voi unique Code + query filter IsDeleted
- DbSets + IApplicationDbContext interface update
- Application: PagedResult + PagedRequest generic
- Application/Master CQRS CRUD 3 entity (Create/Update/Delete/Get/List voi paging search sort)
- Application/Permissions: GetMyMenuTree (union OR role, filter tree), ListMenuItems, ListPermissionsByRole, UpsertPermission (guard admin khong tu giam quyen), ListRoles
- Api/Authorization: MenuPermissionRequirement + Handler (Admin bypass, query DB)
- Program.cs: register 48 policy {menu}.{action} tu MenuKeys x Actions
- Api/Controllers: Suppliers, Projects, Departments, Menus, Roles, Permissions
- DbInitializer: seed 12 menu + admin full CRUD permissions
- Migration AddMasterData + AddPermissions

Frontend (fe-admin):
- Types: menuKeys.ts const, menu.ts (MenuNode/Role/Permission), master.ts (Supplier/Project/Department + SupplierType const-object)
- AuthContext: load menu from /menus/me, cache localStorage, refreshMenu()
- usePermission hook + PermissionGuard component (wrap button)
- UI kit them: Dialog (modal overlay), Textarea, Select
- Generic: DataTable (column config, sortable, loading, empty) + Pagination
- PageHeader component
- apiError helper extract message tu ProblemDetails
- Layout rewrite: render menu dong tu AuthContext.menu (MenuGroup collapsible + NavLink + lucide icon map)
- Pages: master/Suppliers, master/Projects, master/Departments (CRUD + search + sort + paging + Dialog form)
- Page system/Permissions: ma tran Role x MenuKey x CRUD checkbox (tick tu dong PUT upsert)
- App.tsx them 4 route moi

Bug fix:
- MenuPermissionHandler: EF expression tree khong support switch expression -> tach switch ra ngoai AnyAsync
- TS erasableSyntaxOnly khong cho enum -> SupplierType const-object pattern (typeof[keyof])

E2E verified via Vite proxy:
- GET /menus/me -> 6 root + 6 child nodes (12 menus)
- GET /roles -> 12 roles
- POST/GET/PUT/DELETE /suppliers -> full CRUD, soft delete OK
- tsc -b fe-admin pass
