Describe the problem

Only string form fields can use .as('hidden', initial). Number fields cannot use that type.

Describe the proposed solution

Allowing number fields to be .as('hidden'). While we're here, also allowing boolean fields, since there is special-case handling for those.

Alternatives considered

Changing my validation schema and backend API routes to return and accept string IDs instead of numeric IDs.
