perf(faith): warm liturgical cache + fix 1962 rendering

Pre-compute romcal year maps on server boot for current + next civil year
across en/de/la in each rite's default diocese, non-blocking so startup is
unaffected.

Also fixes several 1962-rite rendering bugs: commemorations previously
leaked 1969-shape ids (e.g. andrew_apostle) next to proper 1962 sancti;
station church names came through unresolved because RomcalConfig's
internal i18next has no bundle loaded; season names arrived as raw keys
(advent.season) for the same reason. All three now resolve locally via
the shipped 1962 bundle with Latin as fallback. ClassIV ferias get a
small dot on the grid.
