Add St. Rose of Lima (Aug 30), rank deflated for late canonization

She was previously excluded on a mistaken "post-1617, out of scope"
reading that conflated vu's hour-structure track (Monastic 1617) with
its calendar/saints track (Tridentine 1906 + Divino Afflatu 1954,
which has included her since her 1671 canonization). Her source rank
of Duplex is deliberately deflated to semiduplex, correcting for the
rank creep that made "new canonization" and "Duplex" a near-automatic
pairing from the Baroque period on. She wins Aug 30 outright over Ss.
Felix and Adauctus, who keep their existing commemoration.
