refactor(observability): lower trace sample rate, add DSN comment, improve status visibility

Browse Source 
- Lower tracesSampleRate from 1.0 to 0.1 in both hooks (errors still captured
  at 100%; trace volume reduced for self-hosted GlitchTip on shared VPS)
- Add comment explaining VITE_SENTRY_DSN is a write-only ingest key, safe in
  client bundle — prevents accidental rotation as if it were a password
- Restore HTTP status code prominence: text-4xl font-bold (was text-xs text-ink-3)
- Add min-w-[44px] to copy button for WCAG 2.2 minimum touch target
