Extend the source-file fallback to Frances of Rome/Bibiana, fix a real Agatha/Lucy gap

Follow-up to the previous commit: applies the same "read the fileref
directly, no live query required" fix to St. Frances of Rome and St.
Bibiana, whose own filerefs simply hadn't been derived yet (they predate
the Kalendaria-table work this session built). Both resolve to
common-of-a-virgin, same as several of the 15 fixed previously.

Also swept every saint on the calendar (not just this batch's own
lineage) for any other still-missing collect or Benedictus antiphon,
which turned up a real, older gap: St. Agatha and St. Lucy's own file
comments already documented "resolves honestly missing... despite
propers being set" -- written before collectCommon existed as a
mechanism at all. Agatha's own [Oratio] is a name-substituted reference
confirmed identical to the already-existing collect-c6.yml template, so
collectCommon was simply wired in. Lucy's own [Oratio] references a
different Common formula unedited, with her own [Name] section supplying
the whole descriptive phrase a plain name field would otherwise need the
template for -- written as her own st-lucy-collect.yml rather than a new
single-use template, since she's the only current user of that unedited
form.

St. Clare showed up in the same sweep but is a false positive: her real
content lives in a separate commemoration-bundle file, used via a
different code path the sweep's synthetic-winner methodology doesn't
exercise -- already fully authored, no gap.
