SvelteKit's handleError hook is skipped for expected `error()` throws,
so verses set there never reached `$page.error` for server-thrown 404s
and auth denials. Introduce `errorWithVerse()` in `$lib/server/errorQuote`
that fetches a random verse first, then throws `error(status, body)`
with `{ message, bibleQuote, lang }`, making the quote available in
every `SectionError`. Convert all page load throws (catchalls, layout
validators, calendar, prayers, recipes, fitness, cospend, admin) and
hooks.server auth gates to the helper. Add `src/error.html` as a
branded last-resort fallback.
Replace the emoji/gradient card with an editorial layout: small lucide
glyph, oversized error code, hairline-divided serif bible quote.
Extract shared ErrorView + SectionError components and a bilingual
string helper. Add +error.svelte at each section root (faith, recipes,
fitness, tasks, cospend) so errors render inside the correct layout and
inherit the section-specific header/nav. Catch-all [...rest]/+page.ts
stubs route unmatched URLs through the section layout so the right
error page catches them.
