Implement DOI support and minting

[aaron-collier]

Initially review how DOIs are handled today. Is this in a workflow step, in H2 somewhere, etc?

All we need to do is call Sdr::Repository.register with assign_doi: true. The rest will just work.

I recall that we thought about this when it was built and intentionally did it in a way that was (hopefully) easily reusable. Our future selves are now very happy with this decision!

• Mockup for the collection form where these settings are chosen: https://www.figma.com/design/g46Nfl5EHG7DfwqupK3G4X/H3-2024?node-id=789-4224&t=9soX0awq2YXWVQRo-4
• Mockup with all the use cases for the deposit form. Just click on the "A DOI will/not be assigned text" to see the other use cases. https://www.figma.com/proto/g46Nfl5EHG7DfwqupK3G4X/H3-2024?page-id=1092%3A2227&node[…]width&content-scaling=fixed&starting-point-node-id=1114%3A2853

Note the mockup where the user gets to choose is awaiting one more piece of text to be added.
