Add Patient / View / Edit Patient Page: Need to enforce "If Y, then ..." inputs

[jieqiboh]

There are some inputs that are only valid if another is true or false - e.g. If Y, no. of years for the Past smoking history of a patient.

Need to check that all the inputs are validated to enforce the expected behaviour, since the backend doesn't enforce these conditional inputs.

Will make it so that inputs are disabled unless yes is clicked, if yes is clicked make the input required before they can submit the changes
