 * A single PO Terms & Conditions slot (issue #11) — a native
 * <select name={field}> sourced from the admin-managed clauses for its category.
 * Plain HTML so it works with the forms' native FormData submission.
 *
 * `options` are the active clause texts (also the stored value). `current` is the
 * PO's existing/default value for this slot; if it isn't one of the active
 * options (a removed clause, or an older custom value) it is preserved as a
 * leading "(current)" option so an edit never silently drops it.
