VITE_SENTRY_DSN is already set in Railway as a build arg. The hardcoded
fallback was unnecessary and triggered GitHub secret scanning alerts.

The test error was firing on every production page load — no longer needed
now that Sentry is confirmed working.

- Move React Flow CSS import from component to index.css (CSS layer ordering)
- Add VITE_SENTRY_DSN build arg to Dockerfile for Railway builds
- Use env var for Sentry DSN in instrument.ts with hardcoded fallback
- Add lessons learned #53-55 to CLAUDE.md

Vite env vars must be present during build — VITE_SENTRY_DSN was likely
undefined in Railway's build step, causing Sentry to silently not init.
DSN is a public client key (shipped in every browser bundle), not a secret.

- ErrorBoundary: use Sentry.ErrorBoundary with crash feedback dialog
- RouteError: capture route errors in Sentry (skip chunk load errors)
- User context: set Sentry user on login (frontend + backend)
- Backend: enable profiling (profiles_sample_rate)
- Frontend: add feedback integration, lower replay rate to conserve quota
- Add temporary verification message for production validation
