[SPIKE] Ability to upload emailed documents to MinIO

Documentation Management approach while we are migrating entities and retiring COLIN is in review.

One of the key questions raised to support the decision-making process is whether MinIO has the capability to upload documents directly from email.

Background:

We implemented documents uploading to MinIO from UI. Currently Business Registry filings that support file uploads:
1. Incorporation Application (memorandum + rules) (coops only)
2. Continuation In (proof of authorization + director's affidavit)
3. Voluntary Dissolution (affidavit) (coops only)
4. Special Resolution (memorandum + rules) (coops only)
5. Court Order (staff filing)

Currently, when a supporting document is sent to the Business Registry in the email, staff must print the document, scan it, and then upload it, making it a heavy process that adds unnecessary manual steps.

Could we please investigate the following:

1. Direct Upload from Email:
Is there a way for staff to upload documents directly from an email (e.g., from an email attachment) to eliminate printing and scanning?
2. Existing Solutions:
If there is no out-of-the-box solution, has any similar development work been done for other products or services that we could leverage or adapt?
3. Custom Integration with MinIO:
Would it be feasible to build a lightweight integration layer that captures email attachments and pushes them into MinIO using its API?
4. Other Options:
Are there any alternative approaches that could help us streamline this process?
5. Will it be just easier to integrate with DRS for documents uploading (from UI and emails)?
