fix(ef): adopt eight corrections from colitur, with their citations

lectio's EF data has been the upstream for colitur, whose data was
bootstrapped from this ini. colitur has since validated that data against the
1962 Missal itself, and these eight fields are where the two now disagree and
the Missal decides against us. Each carries the rubric.

Calendar. St Ubaldus (16 May) and St Didacus (13 November) become III-class
feasts rather than commemorations: the Missal's own universal calendarium
ranks both "III classis" outright with no commemoration rubric, and each has
its own Mass entry in the Proprium taking its readings from a Common with
only its Oratio proper -- which a bare commemoration never has. Found by
auditing all 290 of colitur's fixed-date entries against that calendarium;
these two were the only status defects in the file. The Vigil of the
Assumption becomes violet from white and the Vigil of St Lawrence violet from
red: RG 128 gives violet to vigils of II and III class outside Paschaltide,
and its sole exception is the Ascension's vigil, inside Paschaltide, which is
white and is untouched here.

Lectionary. Both Ember Saturdays carried the wrong saint's Mass entirely --
St Thomas the Apostle's under ef-advent-ember-sat and St Matthew's under
ef-september-ember-sat, in both cases because 21 December and 21 September
fall on a Saturday in the same six years and a bootstrap generalised one
year's coincidence into a template value.

Two oracle allow-list entries, both placed ahead of the BVM-Saturday entry
deliberately. When 16 May or 13 November falls on a Saturday, that entry's
predicate also matches and would absorb the divergence under a reason no
longer true of it -- it says both engines agree the day is unimpeded, and the
point here is that the day IS impeded. The vigil entry excludes Sundays for
the mirror reason: RG 33 omits a vigil falling on one, and without the guard
2026-08-09 is stolen from the RG 33 entry that actually explains it.

Six days of the 730-day oracle window are affected. Readings are untouched by
that test, so the two lectionary corrections cost it nothing.
