    CHECKBOX PATTERN: Each checkbox has a companion hidden input that
    carries the actual form value ("true"/"false"). The checkbox itself
    has NO name attribute. JS syncs checkbox.checked -> hidden.value
    on every change and on submit. This avoids all Flask/CKAN issues
    with missing vs duplicate form fields.
