Add July sanctoral content: 11 saints/feasts, fix St. Leo II's wrong date

Continues the full-year sanctoral import: the Most Precious Blood of Our
Lord (Duplex I Classis, full proper office, elevated by Pius XI for the
1933 Redemption jubilee), the Visitation of the BVM (Duplex II Classis,
full proper office), St. Leo II, St. Anthony Mary Zaccaria, the Octave
Day of Ss. Peter and Paul (own real content, not a bare continuation),
Ss. Cyril and Methodius, St. Elizabeth of Portugal, St. Henry, Our Lady
of Mount Carmel, St. Vincent de Paul, and St. Ignatius of Loyola.

Also fixes a real pre-existing bug surfaced while authoring St. Leo II:
an earlier June sanctoral pull had mapped him to "06-28" (his own vita
text mentions his burial "upon the 28th day of June," but his actual
liturgical feast, per the reference engine's Sancti/07-03.txt, is July
3) with no saints/st-leo-ii.yml ever authored for it -- a wrong-date
stub, same class of artifact as the pre-existing St. Apollinaris
wrong-date bug already documented in july-sanctoral.test.ts. Removed
the stale June 28 entry now that he's correctly authored on July 3.

Two day-label tests pinned to Trinity-Sunday-relative dates that now
collide with new fixed feasts (Jul 6: Octave Day of Ss. Peter and Paul)
were moved to collision-free years/dates, and the July stub test
covering "pure octave-continuation days" was updated to a date (July 4)
that's still genuinely unmapped, since most of that range turned out to
have real content after all.
