feat(faith): rename rite URL slugs to vetus/novus

Replace /1962 and /1969 with /vetus and /novus — matches how Catholics
actually refer to the missals (Vetus Ordo / Novus Ordo), reads the same
across de/en/la, and sidesteps the value-laden old-vs-new framing.
Rite pill labels flip to "Vetus" / "Novus"; the year stays visible in
the subtitle. Legacy year-slug URLs 307-redirect to keep bookmarks alive.
