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.

Ora pro nobis sancta Dei Genitrix'). Collect is the saint's own real proper (seven-sorrows-of-the-bvm-collect.yml), unchanged.
