feat(ef): full 1962 universal sanctoral (16 -> 317 celebrations)

Generate internal/caldata/tridentine-calendar.ini from missalemeum's per-date
proper API (Divinum Officium 1962 data) via scripts/gen-sanctoral-ef.go: each
fixed date's observed saint with rank, colour, English name and proper
Epistle/Gospel citations, plus sancti commemorations. Multiple reference years
are tried per date so a saint occulted by a Sunday in one year is still captured
observed in another; saints never observed are ranked commemoration. Feasts of
the Lord are marked class=lord. Latin names hand-curated (missalemeum has none).

Adds TestTridentineLoads, credits missalemeum in NOTICE, bumps to 0.38.0.
