Paperless as a One-Click Deployment

[SpuriousGer]

Paperless is a document management system for PDFs (and emails, Word docs, other office documents).
It offers multiple Docker Compose standard files, see here: https://github.com/paperless-ngx/paperless-ngx/tree/main/docker/compose

There are a few aspects that would make it more complex:

• Dedicated storage volumes on the server (e.g. SMB shares)
• Potentially add auto-backup for those
