[Feature] Create Download Script for Making Backups Locally

### Is your feature request related to a problem? Please describe.

Save backups of games locally too.

### Describe the solution you'd like

Steps probably needed:

- Spin up instance
- Zip Dir's on EC2 together, download as `YYYY-MM-DD--backup.zip` or something. Read from `leaf_config[Volumes][i][EnableBackups]` if you zip it in.
- Ping server every `leaf_config[Watchdog][MinutesWithoutConnections] - 1` to keep alive. (Or maybe just once a minute).
- Verify hashes, delete file on EC2.
- **Don't** turn off EC2, someone might have connected while on. Just let the automation tear it down, and exit.

### Describe alternatives you've considered

Use AWS-Backup. The problem is there's no way to [download from AWS Backup directly](https://stackoverflow.com/questions/63056350/how-can-i-copy-aws-backup-vault-files-to-a-local-server). You could [Restore a recovery point](https://boto3.amazonaws.com/v1/documentation/api/1.35.9/reference/services/backup.html) TO efs, but then why not just download what's already on the Efs/Ec2 mount that's already setup?

### Acknowledgements

- [x] I may be able to implement this feature request
- [ ] This feature might incur a breaking change

No files, tests, or entry points are named. Start by tracing the existing EC2/EFS lifecycle and the leaf_config Watchdog and Volumes settings; compare the AWS Backup and recovery-point references. Done means a local dated backup is downloaded, its hash is verified, the remote file is removed, and the instance is not explicitly turned off.
