Add November sanctoral content (5 saints/feasts)

St. Charles Borromeo (11-04), the Octave Day of All Saints (11-08,
own real Cyprian/Augustine Nocturn 2-3 content, collect reused from
All Saints via cross-id propers), St. Albert the Great (11-15),
St. Gertrude (11-16), St. Felix of Valois (11-20). All Souls' Day
(11-02) deliberately skipped -- a Requiem office, not a normal
saint's office, a genuine mechanism gap.

Several new fixed-date Duplex+ saints displaced existing test
fixtures that had assumed particular dates were clean/ferial/
plain-Sunday: prime.test.ts's MONDAY constant, weekday.test.ts's
clean-Sunday case, and day-label.test.ts's post-Epiphany-overflow
and open-octave-day cases. Fixed by finding genuinely clean
alternate dates/years, never by weakening assertions.
