feat(of): proper readings for the movable Marian memorials

Mary, Mother of the Church and the Immaculate Heart of Mary are computed in the
engine (no fixed-date INI entry), so they fell back to the ferial. Attach their
proper Masses inline: Mary MotC = Gen 3:9-15,20 / Ps 87 / John 19:25-34;
Immaculate Heart = Isa 61:9-11 / 1 Sam 2 canticle / Luke 2:41-51. Verified they
render when observed (Immaculate Heart 2029-06-09). Extends TestOFMovableMemorials.
