feat: improve webhook server and run script integration

- Enhance webhook example with proper shutdown handling using tokio::select!
- Update run.sh to automatically start webhook server alongside main service
- Add event notification configuration to run.sh using environment variables
- Set proper port bindings to ensure webhook server starts on port 3000
- Improve console output for better debugging experience
- Fix race condition during service startup and shutdown

This change ensures proper integration between the webhook server and
the main rustfs service, providing a seamless development experience
with automatic service discovery and clean termination.
