fix(bridge-react): update tests to handle React 19 async rendering

- Replace sleep() with waitFor() from @testing-library/react for proper
  async handling in React 19
- Fix tests that were stuck showing "loading" due to suspended resources
  not resolving properly
- Ensure tests wait for lazy-loaded components to render completely
