rite(ef): fix entry 8's Sunday exception and entry 14's over-restriction

Review of 436ba75 found two calendar defects and one coupling risk.

Entry 8 (All Souls) dropped register line 334's own qualifier,
"(yields to an occurring Sunday)" -- it returned 8 unconditionally,
so on 2 November falling on a Sunday (2025, 2031, 2036, 2042 in the
2005-2050 differential window), All Souls incorrectly outranked and
observed over the Sunday. 2 November is always Time_after_pentecost
and never coincides with any other entry's own date, so the only
rival this exception ever has is an ordinary entry-15 II-class
Sunday; on such a Sunday, band now returns one worse than entry 15's
own value rather than the literal 8 -- strictly worse, not merely
different, since an exact tie would fall to Precedence.resolve's slug
tie-break, which for "ef-all-souls" against a Sunday slug would make
All Souls win the tie anyway. Entry 8's own rank is untouched, so
Task 8's disposition still sees a true I-class candidate to transfer.

Entry 14 (Feasts of the Lord, II class) added a universal-layer
restriction the register's line 341 does not carry -- contrast entry
16 at line 342, which explicitly says "not of the Lord"; RG 37c
(register line 393) also speaks of "II-class feasts of the Lord"
with no universal qualifier. Dropped the layer test: a proper or
indult feast of the Lord now bands 14, not 19/20.

Also exposes vigil_suffix and ember_prefixes from precedence_ef.mli,
matching universal_layer/indult_prefix's existing "colitur convention,
not an RG citation" treatment -- both were previously private literals
duplicated in the test file, so a rename of temporal_ef.ml's slug
format could have drifted silently past both sides agreeing with each
other. Two test rows now build their candidate from Temporal_ef.temporal's
own real output (entry 18's Lent Ember day, entry 21's Ascension Vigil)
instead of a hand-typed slug, closing that specific coupling.

Adds the three cheap rows review named as closing the remaining
unpinned guards (a temporal-origin Class1 candidate on an unnamed
date; a universal Class2 vigil of the Lord; a non-universal Class3
vigil), plus a resolve()-level test proving the Sunday is actually
observed over All Souls, not just that band returns the right integer
in isolation.
