Author common-of-a-confessor Lauds/Vespers bundle (= Confessor-Not-Bishop content)

Fixed a real audit-methodology bug first: the bulk gap-audit was sampling
each saint's own date via prayVespera, which reflects whatever saint
claims First Vespers that evening (often a neighboring day's), not the
sampled saint's own category. Redid it via prayLaudes (no anticipation).

That surfaced the real finding: common-of-a-confessor (37 saints, this
app's largest remaining gap) isn't a distinct liturgical Common -- it's
common-of-a-confessor-not-bishop under a different label. St. Joseph's
and St. Thomas Aquinas's chapter is byte-identical to the already-
authored Sir 31:8-9 text, and several of the 37 saints' own file comments
already say "vide C5" (Confessor Not a Bishop) directly. Not relabeled
across the 37 saint files, since matins-hymn-common-of-a-confessor.yml
and benedictus-antiphon-common-of-a-confessor.yml already establish this
plain id as the real, working one for those saints' Matins/Benedictus
content -- duplicated the Lauds/Vespers bundle under this id too, to
match that existing convention.

Updates two existing tests whose dates collided with this fix: the
FERIAL_MONDAY constant (moved off St. Raymond Nonnatus's own day) and a
new Vespers proof on St. Joseph's First Vespers.
