Author Common-of-a-Martyr(-Bishop) Lauds/Vespers chapter/responsory/hymn/versicle

St. Zephyrinus (Aug 26, common-of-a-martyr-bishop, Simplex) claims First
Vespers over St. Louis's Aug 25, but that evening was showing the plain
ferial hymn instead of a real Common-of-a-Martyr hymn: no content had
been authored yet for this Common category's Lauds/Vespers bundle, so
resolveOfficeBundle's chapter lookup came back missing and the whole
bundle fell through to the ferial default.

Live-verified against Divinum Officium (Monastic Tridentinum 1617)
votive=C2b: chapter Jac 1:12, Lauds hymn "Martyr Dei, qui unicum," Vespers
hymn "Deus tuorum militum," shared versicle "Justus ut palma florebit."
Used the votive-office view rather than a real saint's own day for the
same structural reason as the earlier Confessor-Not-Bishop fix: every
real Common-of-a-Martyr-Bishop saint either has proper content of his own
(St. Lawrence, St. Stephen) or never reaches the rank needed to keep his
own Vespers (St. Zephyrinus, St. Callistus). Cross-checked votive=C2/C2a/
C2b/C2-1 all render identical text, so the same 7 files were duplicated
under the plain common-of-a-martyr id too (St. Hadrian, St. Hermes, St.
Fidelis of Sigmaringen).

Updates one existing Vespers test whose date (2026-03-03) turned out to
also anticipate St. Lucius I's First Vespers, previously masked by this
same content gap; adds two new proof tests and a TODO.md entry.
