Ensure Sign-In button does not hit endpoint when LoginScreens auth form has no entry

[7riumph]

What will this add or fix? 🛠️

Login button hits the API endpoint on each click regardless of if there is an entry.

How might this affect users? 🤔

n/a, but removes unnecessary back-end requests

How should it operate and or look? ( Figma design screenshot 📷 or code flow description )

Acceptance Criteria

• When form page is empty a request cannot be sent

Additionally

• It's good practice to create clear action-oriented commits for each change.
