Give every day of Passiontide its own real propers and label

Passion Sunday through Holy Saturday (14 days) all collapsed onto just
two ids (passion-sunday/palm-sunday) via resolveTemporalId's coarse
governing-Sunday bucketing, so the day-label header showed the same
generic "Weekday in Passiontide" phrase for all 14, and Maundy
Thursday/Good Friday/Holy Saturday silently rendered Palm Sunday's own
collect and antiphons.

Fixed via the same movable-feast override architecture already used for
Corpus Christi/Ascension (calendar/movable-feasts.ts's anchor-based
override), leaving resolveTemporalId itself untouched: each of the 12
non-Sunday days gets its own real winner id, its own authored
collect/Benedictus/Magnificat content, and its own temporal-feasts
display record, closing both the label bug and the underlying content
gap in one mechanism. day-label.ts's temporalLabel and
collectCommemorations also now recognize any named temporal identity
(not just Ember days), so a saint winning outright on one of these days
still surfaces the day's own real name as a commemoration.

A broader audit of every ALWAYS_OVERRIDE_TEMPORAL_IDS entry found the
same class of gap elsewhere: Corpus Christi and Sacred Heart were
completely unauthored across collect/Benedictus/Magnificat/Matins
reading, and Ascension/Trinity Sunday/Christ the King were missing
pieces too. All authored now, live-verified against the reference
engine. Added a general fallback in resolve-common.ts (missing
day-specific content degrades to the coarse Sunday's own instead of
rendering blank) so this class of gap degrades gracefully if it recurs.
