Add Our Lady of Guadalupe (Dec 12)

Sourced from the reference engine's national-calendar file. Own proper
collect, Ant 1, and Matins Nocturn 2 narrative reading (Juan Diego's
apparition account), same scope as the Our Lady of Lourdes feast --
Common of the BVM (C11) carries the rest. No canonization-deflation
question here (an apparition title, cultus confirmed 1754/1910). At
Duplex she ties the Immaculate Conception octave's threshold on a
non-closing day, which favors the occurring saint, so she wins Dec 12
outright.
