calendar: pull July's sanctoral calendar (pre-1955 pull, 7/12)

23 saints for July (18 real + 5 stubs). Caught and corrected a real
mistake in this pull's own methodology: an earlier live-query pass
recorded St. Apollinaris under July 24 based on a year where he'd
actually transferred there (his true date, the 23rd, was a Sunday that
year) — cross-checking against the raw calendar text file
(1570.txt) caught it before it went in. His real date is the 23rd, with
St. Liborius as his (permanently unwinnable) secondary; July 24 is
instead the Vigil of St. James with St. Christina as its own secondary.

Five stubs this month are all genuinely unwinnable (fixed-date
competitors) — the most of any month so far.
