[RBAC-005] feat: Propagate RBAC middleware from erp-core

- Add rbac.middleware.ts with requirePerm, requireAnyPerm, requireAllPerms, requireAccess, requirePermOrOwner
- Add permission-cache.service.ts for Redis caching
- Update shared services and middleware index exports
- Configure construction-specific roles (manager, admin, super_admin)

Propagated from erp-core TASK-2026-01-30-RBAC
