Remove needRecipients and needAwards from Badges
Summary: Fixes T10798. Separates these two since they don't need to be combined and it allows for more flexibility / scalability.
Test Plan:
- Add Badge
- Edit Badge
- Add myself as Recipient
- Remove myself
- Go to my profile
- Award Badge from there
- Assign myself a badge, try to re-assign it, see validation error.
Also, validation errors on dialog forms are ugly.
