Wire seasonal hymn-doxology into every plain-default Lauds hymn

Lauds' Monastic source never carries the "*" substitution marker anywhere
(audited), so this is purely the same deliberate broadening as the Vespers
commit: every plain-default hymn (Sunday, Mon-Sat, Advent, Lent,
Passiontide, Paschaltide) now routes its closing doxology through
getHymnDoxologyId/appendDoxology instead of a fixed ending, split into
matching per-annum companion files that reproduce the original text
whenever no season/feast override applies.
