build(manager): refresh manager/dist with v2.4.0 bundle

- Bumps the embedded manager UI to the version published on
  evolution-foundation/evolution-manager-v2 main, which now includes
  the license-aware login flow that mirrors evolution-go-manager.
- Removes the legacy manager/dist/assets/test-interactive.js stand-alone
  script — its functionality is now a proper React component
  (TestInteractiveModal) inside the bundle, accessed from the instance
  card on the dashboard.
- Updates the manager-v2 submodule pointer to track main.
