Add name-template substitution for Common-of-a-Holy-Woman's invitatory antiphon

Commune/C7's own invitatory antiphon ("Laudémus Deum nostrum * In
confessióne beátæ N..") needs a per-saint genitive-singular name, unlike
every other Common invitatory antiphon currently authored. Exports
resolve-common.ts's existing substituteName helper (previously only used
by getDayCollect for collectCommon/collectName) and wires it into
resolveMatinsInvitatoryText via a new SaintRecord.invitatoryName field
-- kept separate from collectName since the two templates' {N}
placeholders don't always need the same grammatical case. Fills in real
declined names for the 3 saints using common-of-a-holy-woman (Anne,
Martha, Mary Magdalene).
