Port seasonal office content to Lauds, closing the same pre-existing gap

Lauds had the identical issue Vespers started with: resolveOffice only
ever rendered the plain weekday chapter/responsory/hymn/versicle,
year-round, with no Advent/Lent/Passiontide/Paschaltide override —
same source file (Major Special.txt) as Vespers', just never wired up.
Ports the same seasonalOfficeSuffix-based precedence (per-feast/octave
override -> season -> weekday default) and the matching seasonal
content, transcribed the same way as Vespers' own (Monastic hymn
variants applied from the source's substitution notation against each
base Roman text). Paschaltide's chapter is byte-identical to Vespers'
own — the source aliases "[Pasch Vespera] = @:Pasch Laudes" — so both
hours' data files intentionally carry the same text rather than one
importing the other's id.
