[Request]: Storage - Add `container volume cp` command to copy data to and from volumes

### Feature or enhancement request details

Add ability to copy files and directories to and from volumes without requiring a running container. This simplifies volume data management for backups, seeding data, and extraction.

Basic requirements:
* Copy files/directories from host to volume
* Copy files/directories from volume to host
* Preserve file permissions and attributes
* Support recursive directory copying

Example usage:
```
# Copy to volume
container volume cp /path/on/host myvolume:/path/in/volume

# Copy from volume
container volume cp myvolume:/path/in/volume /path/on/host

# Copy directory recursively
container volume cp -r /local/data myvolume:/data
```

This avoids the current workaround of mounting the volume to a temporary container just to copy data in and out.
