Subject: [PATCH] feat(chart): add extraInitContainers, extraContainers,
 extraVolumeMounts, extraVolumes support

Add four extension points to the Helm chart deployment template, allowing
users to inject custom init containers, sidecar containers, volume mounts,
and volumes without modifying the chart itself.

- extraInitContainers: runs before the main container
- extraContainers: sidecar containers alongside the main container
- extraVolumeMounts: additional mounts in the main container
- extraVolumes: additional volumes for the pod
