fix(vacaciones): edit and delete vacation ranges

Vacaciones ranges could be created but never edited or removed --
EstadoAlarmas already had crearRangoVacaciones/eliminarRangoVacaciones
with no UI affordance reaching them, and no update path at all.

Add EstadoAlarmas.editarRangoVacaciones and wire tap-to-edit /
swipe-to-delete (with confirmation) onto every range card, mirroring
the alarm list's own Dismissible + confirm-dialog pattern exactly. This
covers the active-range hero too: a freshly created range is active
immediately and only ever renders there, never in the
scheduled/past lists, so it needed the same affordances or a user's
very first range could never be fixed.
