calendar: move St. Hilary of Poitiers to his real date, Jan 14

Confirmed against the raw [Officium] file directly: Jan 14 is Hilary
(Latin/Sancti/01-14.txt), Jan 23 is St. Raymond of Peñafort
(Latin/Sancti/01-23.txt) -- not Hilary at all. The original Jan-23
placement wasn't fabricated, just misled by its own source: 2029 is a
real year where Jan 14 falls on a Sunday and every day through the
22nd is already occupied by another feast, so Hilary genuinely
transfers all the way to the 23rd that one year -- the app had
mistaken that transfer-year artifact for his real, fixed date.

His collect text is unaffected (a feast's collect doesn't change based
on which day it's said), re-confirmed identical on his real date.
Benedictus antiphon pulled fresh, completing January's antiphon pass
(9/9).
