Data Source updates, approval, maintenance

[josh-chamberlain]

Context

We have #74 for approving brand new sources (and requests). We should also be able to approve updates to sources that come from external sources. This is more complicated.

These could come one by one, or via script. (example of a third party script)

Requirements

• [ ] allow people to propose changes programmatically or via data-sources/edit UI
• [ ] allow people to approve or deny changes

Option 1, Using dolthub:

• mirror our db to dolthub, and let them handle the merge and approval process
• document the process of making suggested changes
• when changes happen in dolthub, sync them back to our production database

dolthub docs: https://docs.dolthub.com/

Option 2, Using retool to roll our own:

• back end support for proposed updates
• add a page to the retool workflow for approving proposed updates
• deal with conflicting updates (rare but scary)
• deal with approving many things at once (seems complicated)

We have to decide on an approach, then detail it.
