fix(of): partial-proper memorials compose proper part + ferial (match USCCB)

A memorial marked 'PROPER Gospel' (Guardian Angels, Mary Magdalene, Our Lady of
Sorrows, Joseph the Worker, the Passion of John the Baptist, Sts Martha/Mary/
Lazarus) uses the FERIAL first reading + its proper gospel; one marked 'PROPER
First Reading' (Barnabas) uses its proper first + the ferial gospel. Previously we
imported catholic-resources' *suggested* first for the gospel-proper ones, which
differs from what USCCB publishes.

- readings.go: when the observed's inline Mass has only a proper gospel (or only a
  proper first), fill the missing reading/psalm from the day's ferial and sort into
  canonical order. A fully-proper feast is untouched. Factored out ofFerial().
- gen-of-sanctoral-readings.py: keep only the strictly-proper part per the CR
  source-note.

Verified vs USCCB: Guardian Angels (2025-10-02) now = Nehemiah 8 / Ps 19 /
Matt 18:1-5,10 exactly. Updates TestUniversalSanctoralReadings.
