fix(of): dispatch Holy Family's Normae n.35(a) fallback (W2)

temporal_of.ml's temporal only ever reached holy_family's own correct
26-31 December / 30 December fallback logic through sunday_slug, which
returns None immediately for a non-Sunday date. In a year 25 December
is itself a Sunday (26-31 December then holding no Sunday of its own),
the feast vanished entirely and fell through to an ordinary Christmas
ferial slug -- confirmed on 2022, 2033, 2039, 2044, 2050 (and roughly
1583..9999 domain-wide, one year in seven).

temporal's dispatch now consults holy_family directly, independent of
weekday, between the sunday_slug and christmas_feria_slug branches,
carrying the identical identity the Sunday case already builds
(subject Lord, holy_family_names, rank Festum). holy_family and
anchors were already correct and needed no change.

Added a direct example-based test for the fallback across five
affected years plus a control for the unaffected Sunday case, and a
domain-wide property (Holy Family is observed in every liturgical
year 1583-9999) folded into both the 200-sample QCheck run and the
exhaustive sweep -- the property that would have caught this directly.

Un-pinned the now-fixed behaviour everywhere it was recorded as
known-wrong: test_rite_of.ml's own 1583 pin (rewritten to assert the
fix), test_validate_of.ml's own independent exhaustive-sweep counter
and landmark-year filter (found via make check, not the initial
survey), and data/of/expected-divergences-litcal.sexp's L2/L3
allow-list entries against the litcal oracle (closed and removed, with
a dedicated regression test replacing the allow-list's own silence).
