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.

+`prayVespera` to sample each saint's own date, but Vespers reflects whatever saint claims First
+Vespers *that evening* — often a neighboring day's saint, not the sampled saint's own category.
+Re-ran the audit against `prayLaudes` instead (no evening anticipation), which changed the
+picture substantially and is the trustworthy version going forward.
+
+**Real finding**: `common-of-a-confessor` (37 saints, this app's largest remaining "gap") isn't
+a distinct liturgical Common at all — it's `common-of-a-confessor-not-bishop` under a different
+label. Confirmed live: St. Joseph's (Mar 19) and St. Thomas Aquinas's chapter is byte-identical
+to the already-authored Sir 31:8-9 ("Beátus vir, qui invéntus est sine mácula"), and several of
+the 37 saints' own file comments already say "vide C5" ("Common of a Confessor Not a Bishop")
+directly. Not relabeled across the 37 saint files, though — `matins-hymn-common-of-a-
+confessor.yml` and `benedictus-antiphon-common-of-a-confessor.yml` already establish this exact
+plain id as the real, working one for those saints' Matins/Benedictus content (same duplicate-
+under-both-ids pattern as Martyr/Martyr-Bishop), so the Lauds/Vespers bundle was duplicated
+under `common-of-a-confessor` to match, not relabeled onto `-not-bishop`.
+
+Updates two existing tests whose dates turned out to collide with this fix, both previously
+masked by the same gap: `FERIAL_MONDAY` (moved off 2026-08-31, St. Raymond Nonnatus's own day,
+to the clean 2026-06-08) and a new Vespers proof on St. Joseph's First Vespers (2026-03-18).
