UI for adding users to acronyms

[loneil]

Description

https://apps.nrs.gov.bc.ca/int/jira/browse/SHOWCASE-1737 Interface for adding users to acronyms so we don't need the hacked api tester GET endpoint. Show list of existing acronyms to pick from (or add new). Will send the email so you don't have to go over to Outlook and do the copy paste stuff. If you need to have additional conversations (beyond the simple comment supplied), can respond to the user with the CC'd email in the team inbox.

Types of changes

New feature (non-breaking change which adds functionality)

Checklist

• [x] I have read the CONTRIBUTING doc
• [x] I have checked that unit tests pass locally with my changes
• [x] I have added tests that prove my fix is effective or that my feature works
• [x] I have added necessary documentation (if appropriate)

Further comments

Can test out using whatever existing acronym or creating new ones on this PR, it's just database records on the temp DB. Do not do any service client api access promotion after or do anything in Keycloak as part of testing (no keycloak usage needed for any of this process ever)
