• I added support for custom endpoints in the backend framework. Previously I was registering the endpoint directly at a high level, but I think the new solution is more graceful as it registers it at the appropriate level (in user.ts). You can see previous solution in this commit
• I added a new database function to bundle users with organizations in one query. Previously it would pull each affiliation separately for each user which is not ideal. Previous solution is visible in this commit
• src/front-end/typescript/lib/app/update.ts edit was necessary since it started to throw a typescript error there after related imports
• Front end performance is low when there are a lot of users in the list (interacting with modal is slow). There's a PR from Kaegan where he worked on performance on that page, so I'll re-visit this once I get to that PR.

• now using the endpoint from a separate resource (needed to use readMany for the right url structure, but it seems to be working well)
• replaced user types with enums
• put validation into proper place
• made use of userTypeToTitleCase (moved to shared library)
• implemented existing checkbox and formfield components
