preventing forms from submitting when enter key is pressed

[ckd002]

Description

When a user was filling out a form, hitting the enter key would result in the form attempting to submit. If the user did this and all other fields were filled in, it would submit even if the user wasn't ready for it to do so. This fix prevents the application from attempting to submit the form when the enter key is pressed while maintaining the ability to use the enter key in fields where multiple lines are accepted.

Validation Steps

This will help us get a jump start on validating your PR by describing the steps to replicate
and validate the expected behavior. (For an example of good validation instructions, check out Bryan's Bouncy Ball PR.)

1. Make sure all merge request checks have passed (CI/CD).
2. Pull related branches locally.
3. Navigate to the DAR form
4. Click on each form element and then hit enter to verify that the form doesn't submit
5. Repeat step 4 on a DER form (Yes this is necessary because the fix is handled on an input basis so not everything is covered by the first form)
6. Repeat step 4 for a DPR form
