Author Matins invitatory-antiphon Common tier for Confessors/Martyrs/Virgins/Dedication

resolveMatinsInvitatoryText's Common-category tier existed but only had
Common-of-an-Apostle authored, so every other Common category fell all
the way through to the plain ferial invitatory antiphon regardless of
rank (e.g. St. Joseph Calasanctius, 2026-08-27, Confessor). Adds the
Confessor family (5 duplicated ids, matching the hymn's own precedent),
Martyr family (2 ids + Several Martyrs), Virgin family (2 ids), and
Dedication — all read directly from the reference engine's own
Commune/C-number [Invit] lines. Holy Women (C7) needs a name-template
mechanism this project doesn't have yet for invitatory antiphons, and
General/All Saints (C9) turned out to be a mislabeled backlog item (C9 is
actually the Office of the Dead) — both logged in TODO.md instead.
