refactor: remove verbose logging and use explicit exception types

- Remove verbose warning/debug logs from ServerConnectionCheckJob and ContainerStatusAggregator
- Silently ignore expected errors (e.g., deleted Hetzner servers)
- Replace generic RuntimeException with DeploymentException for deployment command failures
- Catch both RuntimeException and DeploymentException in command retry logic
