Label unattributed hagiographic Matins readings by saint, not "Reading"

A saint's vita reading (Nocturn 2, no patristic `source` attribution)
fell through to the UI's generic "Reading" heading. Add
fallbackHagiographicLabel, which looks up the contributing id's own
saint/temporal-feast record and produces "On St. Pius X, Pope and
Confessor" style labels instead — same plain-string convention as an
authored `source`.

Updates two matins.test.ts assertions that used label shape (string
vs object) as a proxy for "not a bible-plan reading" — no longer
reliable now that vita readings also carry a string label, so they
key off citation presence instead.
