fix(rbac): register user:manage and vm:manage, close legacy map gaps

These permissions were referenced by the API (users.manage, proxmox.vm.manage)
but never registered in the permission registry, so they only worked through
the is_admin bypass — non-admin users granted them silently received 403.

- Register user:manage and vm:manage in the registry.
- Add missing legacy mappings: users.manage->user:manage,
  settings.manage->setting:manage.
- Grant both new permissions to the admin role (defaults + init.sql seed);
  ensure_default_roles_new_format propagates them to existing deployments.
