Improve daemonset startup diagnostics and increase timeout

- Increase waitDaemonset timeout from 50s to 5 minutes (30×10s)
  * CI environments often have slow image pulls
  * Previous timeout was too aggressive for registry operations

- Add comprehensive diagnostic output on pod startup failure:
  * Pod status with node placement (get pods -o wide)
  * Recent events to identify ImagePullBackOff, etc
  * Pod event details from describe output
  * Daemonset logs if containers started

This helps diagnose ContainerCreating issues in CI where pods
fail to start due to image pull problems or resource constraints.
