hours: add the day's-collect resolver

Terce/Sext/None's Oratio is the day's own Proper-of-season/-saints
collect, not a fixed text — getDayCollect() resolves it from the
LiturgicalDay's winner (temporal id or sanctoral saint's propers),
falling through to an honest "missing" status for saints that don't
have authored propers yet.
