Add St. Joseph's suffrage; fix Cross/BVM suffrage gating

Three things prompted by today's date resolving wrong:

1. St. Joseph's own Lauds suffrage was never modeled at all. Added
   lauds-suffrage-joseph.yml, sourced from Tridentine 1906/1910 (the
   reference engine's "Tridentine - 1906" version) per direct
   instruction -- Monastic 1617's own suffrage set has no Joseph
   suffrage at Lauds, so this one genuinely comes from a different track
   than the other four.

2. The Cross suffrage's actual gating rule, live-verified against a
   plain ferial win, a plain Sunday win, a low-rank saint's own win (even
   bare Simplex), and Marian Saturday: it shows only when the bare
   temporal feria itself is what's being prayed -- the opposite of
   "Sunday or a feast of the Lord." Expressed as `!isSundayOrFeast(day)`
   (the same ferial/festive split Prime's capitulum already uses) plus
   one more exclusion for a named temporal identity like Marian Saturday,
   which isn't Sunday or a sanctoral win either but still isn't a bare
   ferial office.

3. The BVM suffrage is correctly dropped on Marian Saturday (unchanged
   behavior, just now understood and commented correctly): it's specific
   to a day whose own office is already Marian, confirmed via the same
   live source, not a guess.

Also models St. Clare (Aug 12, Simplex under Monastic 1617) and surfaces
active octaves in getDayLabel, since today's date was resolving as a
plain ferial day instead of showing St. Lawrence's octave with St. Clare
commemorated.
