fix(kernel,rite-ef): admit orders commemorations by RG 113's table of precedence, not slug

Precedence_ef.admit broke a same-rank tie among commemoration candidates
alphabetically by slug -- a deterministic engineering convention with no
rubrical citation. RG 113's own second sentence, primary-source-verified
against two independent scans and previously uncited in the register
(only "commemoratio de Tempore fit primo loco" was quoted before), gives
the real rule: "in admittendis et ordinandis aliis commemorationibus,
servetur ordo tabellae praecedentiae" -- admitting and ordering
commemorations both run on the rite's own table of precedence (band's
28-entry table), not RG 8's coarse four-class rank.

Precedence.resolve now computes each commemoration candidate's own band
value once, generically, and hands it to rules.admit as a third tuple
element (Precedence.rules.admit's signature changed accordingly, ditto
Precedence_ef.admit; every rule-record stub in the test suite updated to
match). Precedence_ef.admit's own compare_dignity is replaced by
compare_precedence, ordering by band then slug; a residual tie within one
identical band value still falls back to slug, since RG 113 gives no
further instruction there -- documented as a still-uncited engineering
convention, not dressed up as a rubric.

RG 98 ("in paritate autem Officium prius impeditum praecedit") was
considered as a candidate authority for that residual and rejected: it
governs the transfer queue order among several simultaneously-impeded
I-class feasts (Caput XIII), a different operation in a different
chapter from RG 113's commemoration admission (Caput XVI); nothing in the
primary text connects the two.

Blast radius measured against the pre-change binary across the entire
1583-9999 domain (not only 2005-2050): the admitted-commemoration-slug
set is byte-identical, day for day, before and after this change. The
fix corrects the citation and mechanism, not the answer, on this
codebase's current data -- both of the task brief's named examples
(22 Feb Chair-of-Peter/Lent-vs-Paul, 22 Sept Maurice-vs-Thomas-of-
Villanova) are confirmed present and unchanged in both streams. A new
test (RG113: admit picks by precedence order, not slug, when they
disagree) proves admit actually consults the passed-in precedence value
with a synthetic pair whose slug order and precedence order disagree --
teeth a same-band-only regression test could not have caught, since
every real collision found in the domain happens to agree on both axes.

271 -> 272 tests, all green; COLITUR_EXHAUSTIVE_SWEEP=1 unaffected.
