Give Ascension its own hymnody at Matins/Lauds/Vespers, all octave

`ascension` is a temporal-feast id, not a saint record, so
resolveOfficeWinner's octave-synthesis (which already handles
saint-based octaves like Assumption's/St. Lawrence's) never
recognized it -- Ascension Day itself and its whole octave silently
rendered the generic Paschaltide hymn at every hour.

Fixed the mechanism: added `ascension` to ALWAYS_OVERRIDE_TEMPORAL_IDS
(covers the feast day itself), and taught resolveOfficeWinner to also
synthesize a {kind:'temporal'} winner from an active octave with no
saint record but a real temporal-feast record (covers ordinary-feria
octave days; a real winning saint within the octave still correctly
keeps priority).

A third gap surfaced testing this: octaveGoverningPrivilegedDay's
correct-by-design "a privileged Sunday never accepts an octave
override" rule is live-verified wrong specifically for "Dominica
infra Octavam Ascensionis" (keeps the octave's own hymn/responsory,
just with its own distinct proper chapter). Rather than loosen that
shared gate for every octave, gave resolveLaudsHymn/resolveVespersHymn
a narrow, hymn-only intercept guarded to saint-less octaves, checked
before the season/weekday default.

Authored matins-hymn-ascension.yml, lauds-{capitulum,responsory,hymn,
versicle}-ascension.yml, and vespers-{responsory,hymn,versicle}-
ascension.yml (Vespers reuses Lauds' chapter via the existing
cross-hour fallback) -- all live-verified against Divinum Officium
(Monastic Tridentinum 1617), 2026-05-14.
