fix: make all docs consistent with version prefix and grouping in sidebar

[JoeCap08055]

Problem

Docs sidebar for different services/controllers was inconsistent; showing the version prefix path for some, and not others.

Solution

Utilize Redocly x-tagGroups extension to group controllers with different versions nested under the controller group. Only affects docs.

Steps to Verify:

1. Run npm run generate:openapi
2. Run npm run generate:swagger-ui
3. Inspect docs for each service to see changes
4. Run each service & browse to the live Swagger UI; should be no change from previous (Swagger UI doesn't support tag groups)

Screenshots (optional):
