fix: Add comprehensive LocalStack connectivity diagnostics to CI

- Test port 4566 connectivity with netcat before health check
- Show Docker container status if connection fails
- Display full health response for debugging
- Show LocalStack container logs if health check fails
- Helps diagnose why tests can't connect to service container
