When "None of the above" was selected and the notes field was already
visible but empty, pressing Enter re-opened the notes field endlessly
because the guard only checked !notes (empty string is falsy).
Add !notesVisible guard so auto-open only triggers on the initial
selection, not when the user is confirming from an already-open notes
field.
