Summary:
Fixes T4065. This divides user creation into separate "Standard User" and "Script/Bot" workflows which show only relevant fields and provide guidance.
This fixes the verification mess associated with script/bot users by verifying their email addresses automatically.
Test Plan:
- Created a standard user.
- Created a script/bot.
