Fix St. Gabriel's Lauds/Vespers capitulum copy-paste bug

lauds-capitulum-st-gabriel-archangel.yml carried Apparition of St.
Michael's own capitulum ("Significávit Deus...") under Gabriel's id --
found in passing while authoring his Matins psalmody. His real
capitulum, read directly from the reference engine's Sancti/03-24.txt
([Capitulum Laudes]), is Daniel's own account of the angel's visitation
(Dan 9:21-22), genuinely proper to Gabriel, not shared with Apparition
despite sharing the same hymn. No separate vespers-capitulum file exists
for this id, so the fix covers both hours via vespersCapitulumForOverride.

Updated tests/hours/lauds.test.ts: removed Gabriel from the shared-
chapter assertion loop (Guardian Angels/Raphael still legitimately share
Apparition's chapter, confirmed via their own saint files' explicit
source cross-references) and added a dedicated test for his own chapter.
