Required fields and form submission validation in Forms

Add an option in the Forms tab that allows designating certain fields as required before a patient can submit a form. Currently, patients can submit forms with important information missing, yet the system still marks those forms as completed — for example, credit card authorization forms where patients enter their card information but leave the expiration date blank, so the form appears completed even though essential information is missing. This creates unnecessary back-and-forth communication, additional administrative work, and potential liability concerns, particularly for documents such as informed consent forms, where a form may appear signed and completed despite missing required information. Suggested behaviour: a "Required Field" option when creating or editing forms; if a required field is left blank, the patient receives a notification identifying the missing information and is unable to submit the form until it is completed. Ideally, the system would also distinguish between forms that are fully completed and those that have been submitted with missing information. This would help ensure that important documentation is complete, reduce unnecessary follow-up communication, and improve both the patient and provider experience.
