Author Common-of-a-Confessor-Bishop Lauds/Vespers chapter/responsory/hymn/versicle

Third Common category (17 real users) with no Lauds/Vespers bundle
authored. Live-verified against Divinum Officium (Monastic Tridentinum
1617) votive=C4: chapter Sir 44:16-17 "Ecce sacérdos magnus," Lauds hymn
"Jesu Redémptor ómnium," shared versicle "Justum dedúxit Dóminus per vias
rectas." Found the Vespers hymn is byte-identical to Common-of-a-
Confessor-Not-Bishop's own ("Iste Conféssor Dómini sacrátus") even though
the chapter, both responsories, and the Lauds hymn all genuinely differ
between the two categories -- reused that already-authored text verbatim
rather than re-deriving it.

No real Duplex-II-classis+ saint exists in this category, so the Vespers
proof uses St. Ubald's real First-Vespers anticipation instead of a
votive-only proof. Updates one existing test (2026-04-20, Paschaltide
seasonal office) whose date turned out to also anticipate St. Anselm's
First Vespers, previously masked by this same gap.
