Author common-of-an-abbot Lauds/Vespers bundle (= Confessor-Not-Bishop content)

Same finding as common-of-a-confessor: live-verified (St. Maurus, Jan 15;
St. Odo, Feb 7) that Common-of-an-Abbot's real Lauds/Vespers content is
identical to Common-of-a-Confessor-Not-Bishop's -- an Abbot isn't
necessarily a bishop, so the traditional rite reuses the plain Confessor
common for them. Duplicated the same 7 files under this id, matching the
existing benedictus-antiphon-common-of-an-abbot.yml precedent. Proof
tests on St. Maurus (Duplex II. classis, own Lauds + real First-Vespers
anticipation Jan 14 -> 15).
