B6 Form GDS auto calculation (checklist updated)

This PR focuses on the calculation of the fields

Original Review Specs

• GDS score should auto calculate as user selects each radio button option
• If any question has an option of Did not answer = 9 GDS score should be set to 88
• GDS regular expression validation should be updated to allow 0
• Form finalizes when all radios are input and NOGDS is false
• Form gives an error when NOGDS is not checked and not all radio inputs are answered (unanswered radios display the error)
• Form partial saves

Added Specs

• GDS (question 16.) is a read-only field (from UDS3)
• Unchecking the NOGDS checkbox will recalculate the GDS field with currently selected radio values
• Radios selected while NOGDS is checked will result in the GDS total still being 88

Spoke with Josh, bringing over functionality from UDS 3

• Disable radio buttons when NOGDS is checked

We will not be focusing on disabling in this PR while we further inspect the form guide

Modified the logic to remove disabling the radio buttons, in this PR we only want to run the auto calculations. Spoke with Ash about the form logic and we agreed to revisit the disable validation in a later card after inspecting the form guidelines further
