ALCS Document & Decision Document form reset bug

**Jira Ticket**: ALCS-2165

Select document name in upload modal and hit enter > resets form

AR: When I want to edit a document that i have added on ALCS, and when I have selected the document name field and hit enter, the form gets reset.

AR: Same thing happens on decision document modal, if i hit enter it clears the form. But it gets a bit worse since I can't upload file after that. I have to close the modal and open again

ER: Attempt to save data, run validation and if user hasn't filled out all the fields, then show error states.

Start by reproducing the reset after pressing Enter in the ALCS document upload and decision document modals, then trace their form submission and validation handling. Done means Enter attempts to save, validation errors appear for incomplete fields, and the form and upload flow remain usable without reopening the modal.
