Author Common-of-a-Confessor-Doctor and Common-of-an-Apostle Lauds/Vespers bundles

common-of-a-confessor-doctor (4 saints) is another "same content,
different id" case: live-verified votive=C4a byte-identical to plain
votive=C4 (Common-of-a-Confessor-Bishop), so duplicated verbatim rather
than authored fresh, matching the already-existing matins-hymn-common-
of-a-confessor-doctor.yml precedent.

common-of-an-apostle (3 saints/feasts) is genuinely distinct: chapter
Eph 2:19-20, hymn "Exsúltet cælum láudibus" (byte-identical Lauds/
Vespers), shared versicle "Annuntiavérunt ópera Dei." Also duplicated
under the separate common-of-apostles (plural) id used by the Octave of
Ss. Peter and Paul.

Proofs: St. John Damascene (own day) + St. Robert Bellarmine (First
Vespers) for Confessor-Doctor; Commemoration of St. Paul (own day) + the
Beheading of St. John the Baptist (First Vespers) for Apostle.
