fix: update tests for RichEditor form data paths and service providers

Update all tests to use new form state paths (commentData.body,
editData.body, replyData.body) instead of removed public properties.
Remove searchUsers() tests (method replaced by MentionProvider).
Add BladeUI Icons service providers to TestCase for RichEditor views.
