ver_formulario_enviado: auto-fill hora on Minuto 0 (fresh form)

_mpAutoFillHora was gated behind hayFirmaIniciada, so it never ran
on a fresh form where no signatures exist yet. Now always fills the
hora field of the first visible firma widget; scroll only when at
least one signature has already been saved.
