feat(faith/apologetik): voice routing + Alex's choice chip

- contra/pro detail pages move from #voice-X hash to /[argId]/[archId]
  (and /[posArgId]/[voiceId]) optional path segments. SSR renders the
  selected voice directly — no hydration flash on deep links.
- Tab onclick uses replaceState to update path without a load roundtrip.
- Add Alex's choice chip on contra detail tabs: small circular pfp on
  picks, expanded label on the active tab. ALEX_PICKS map per argument.
- Answer-rail pills on contra index extend past 760px column into the
  right viewport gutter when space allows; wrap otherwise.
