CNFT1-3223: Remove handling of blur event to prevent persistent error display (PR preview)

[joeaxcdw]

Description

This is a Preview PR for upcoming team change.

PRs should contain:

• A decent, descriptive summary of the change
• Unit test addition or changes based on the UI changes.
• An optional screenshot to convey the visual changes to the reviewer.

Remove handling of blur event to prevent persistent error display on status checkboxes.

Note: This is a temporary fix. The permanent fix is to handle the blur event at the CheckboxGroup level, so that error only shows when user tabs away from checkbox group completely.
