calendar: give Advent's ordinary ferias their own precedence tier

Found while starting the December sanctoral pull: Advent's plain (non-Ember) weekday ferias have real standing in the live Monastic 1617 engine that the existing ordinary-feria category couldn't represent -- a Simplex saint (St. Bibiana, Dec 2) is merely commemorated there rather than winning outright, while a Semiduplex+ saint (St. Nicholas, Dec 6) wins with the feria itself commemorated back. Adds a third, weaker privileged-feria-minor tier (Semiduplex+ threshold, vs. privileged- feria's Duplex+) rather than reusing either existing tier, mirroring how privileged-feria/privileged-feria-major were split in March. Lent's own ordinary ferias likely share this property but are left as-is, unverified this session. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

  # Christmastide's ferias are folded into the privileged-feria default for
  # the whole season as a simplification of "the Octave of Christmas (Dec
  # 25 - Jan 1) is privileged" — slightly overbroad into Jan 2-5, harmless.
