#8737 Package standalone mods on save - Slice 1

[BLoe]

What does this PR do?

• Closes #8737

Discussion

• I removed the widerLabel thing because it was making the create mod modal look bad, too much white space and the user scope input squished. I went through other usages and they were all super weird and/or didn't seem to affect the UI at all.

Remaining Work

• [ ] Fix issue(s) identified by the end-to-end tests
• [ ] Fix any remaining merge conflicts
