Give the Matins ferial hymn its own text per weekday, not one for all

Browse Source 
matins-hymn-ferial.yml turned out to already be Monday's own hymn
("Somno reféctis ártubus"), mislabeled as a single fixed year-round
text and used unconditionally for every weekday -- the source
(Psalterium/Special/Matutinum Special.txt) genuinely varies this hymn
Monday through Saturday, the classic "week of hymns". Caught first on
Friday ("Tu Trinitátis Únitas" expected, Monday's text shown), then
again on a real Ember Saturday ("Summæ Deus cleméntiæ" expected).

Authored matins-hymn-ferial-{tuesday,wednesday,thursday,friday,
saturday}.yml (Monastic 1617 text, live-verified against the CGI
instance directly, including Friday's own real M-track word-swaps) and
wired resolveMatinsHymn's final fallback tier to pick by day.weekday.
Sunday is left on the existing placeholder, documented as a real,
more complex not-yet-understood gap (a two-hymn source split).
