Closes the gap this whole sweep started from: Nocturn 3 on post-pentecost-13/14 showed St. Augustine's homily with no Gospel citation or text above it. Fixes all remaining post-pentecost-NN ids (01-14, 16-24; -15 already had this from the original mechanism proof) the same way as the rest of the sweep, plus Trinity Sunday's second Nocturn 3 pair — the "Commemoration of the First Sunday after Pentecost," whose Gospel (Luke 6:36-42) has no live date to source from since Trinity always occupies that slot, so it's sourced from the reference engine's preserved pre-displacement Mass propers file instead. Also fixes a stray-space formatting glitch in post-pentecost-19's existing homily text, found while sourcing.
