fix: Fix test failures across different ActiveAdmin versions

- Update CSS loading test to check for Quill styling in a more robust way
- Handle nested resource test differently for AA2/3 vs AA4 due to has_many behavior differences
- Fix RuboCop Layout/ExtraSpacing offenses in Appraisals file
- Tests now pass for AA4 and gracefully skip incompatible tests in AA2/3
