Finish the sanctoral commemoration bundle sweep (213/218 saints)

Follow-up to the earlier bulk pass. Sourced the remaining category
templates: BVM feasts (13, reused the already-verified BVM suffrage
versicle plus each feast's own antiphon), angels (4, versicle inferred
from a saint file's own "structural category" note), Confessor-Doctor/
-Pope (7, resolved to C4a/C5a/C4b -- each inheriting its base category's
Ant2/Versum2 unchanged, no new content needed), several confessors and
apostles-plural (2, reusing already-sourced category versicles), and 5
fully-proper feasts (All Saints x2, Finding of the Holy Cross, Most
Precious Blood, Transfiguration, Our Lady of Ransom) given their own
real Ant2/Versum2 straight from their Sancti files.

213 of ~218 real saints now covered. Only the 5 Vigils remain open --
no dedicated Commune template exists for that category in the reference
engine, and FeastClass 'vigil' rarely reaches the commemoration code
path anyway.

+    against the evils of the present life on earth, that we may enjoy its everlasting
+    fruit in heaven.
+    Through the same Jesus Christ, thy Son our Lord, Who liveth and reigneth with thee,
+    in the unity of the Holy Ghost, God, world without end.
+    ℟. Amen.
