Use structured fields for form response `value` entry

[evadecker]

Is your feature request related to a problem? Please describe.
Currently, values in /settings/responses accept plain text input, but some fields store a boolean, an array, or other structured data.

Describe the solution you'd like
It would be nice to display UI which is associated with the stored data type. (E.g. a checkbox or a switch for boolean, a checkbox group or dropdown for array, etc.)

Describe alternatives you've considered
