src/App.tsx (Scripture Index book map) and server/routes/bible-passage.js
(BSB/bolls.life passage fetch) each hand-maintained their own independent
66-book list with a different key format (3-letter USFM id vs bolls.life's
numeric id), so a future alias/rename fix in one would silently not apply to
the other.
Add shared/bible-books.js as the single canonical list (name + aliases +
USFM id, in canonical order); the server derives its numeric bolls.life ids
from the array position instead of hand-maintaining a second table. Requires
allowJs + including shared/ in tsconfig.app.json so the client can import the
plain-JS module alongside its TypeScript sources.
