Full precedence sweep of temporal-categories.yml, two more real bugs

Following the Ascensiontide fix, swept every remaining unverified Sunday/
feria precedence tier against the live reference engine:

- commemorations.ts's privileged-sunday rule was itself wrong: a
  duplex-majus+ candidate was given a bare commemoration instead of
  transferring, never actually verified. Live-checked the Immaculate
  Conception (transfers off Advent II) and the Annunciation (transfers
  off Palm/Easter Sunday) - confirmed correct by direct instruction.
  privileged-sunday now transfers every rank unconditionally.

- eastertide's own Sunday tier was backwards (privileged-sunday instead
  of ordinary-sunday) for the ordinary Sundays after Easter - live-
  verified twice (Finding of the Holy Cross, St. Mark both win outright).
  Easter Day itself still needs the stronger tier, now special-cased
  directly since Sundays never consult the offset table.

Six existing tests updated to reflect real, live-verified behavior - each
had the old wrong "commemorated in place" assumption baked into its
expected value. Remaining unverified entries (Vigil of Pentecost/
Christmas, Corpus Christi/Sacred Heart) documented as such rather than
silently assumed correct.
