propers: add August's collect and antiphon text
11 collects, 4 antiphons -- including backfilling the three pre-existing
August entries (Lawrence, Assumption, Augustine) now that the pulling
methodology exists. Also updates three pre-existing tests whose dates
collided with this month's new real content: the vigil-of-St.-Lawrence
backward-transfer case now runs into a real feast at its landing day
instead of an empty one (confirmed correct against the live reference
engine, including the surviving commemoration on the impeded Sunday
itself), and two other tests moved off Aug 9/10 to dates unaffected by
the new data.

// commemorations.ts's ordinary-sunday rule) and must transfer backward.
// Since the August pull, Aug 8 is no longer an empty landing day — Ss.
// Cyriacus, Largus, and Smaragdus (Semiduplex, a fixed, non-movable
// date) natively occupy it every year, so the backward-transferred
// vigil runs into collision.ts's sanctoral-vs-sanctoral rules instead of
// landing untouched: Semiduplex outranks 'vigil' on the shared
// FeastClass scale, so Cyriacus wins and the vigil is commemorated
// rather than displacing him — real transfer+collision interaction, not
// a data error, same class of finding as July's Apollinaris/Vigil-of-
// St.-James case.
