Add ALLOW_RAILWAY_ORIGINS env var that enables regex-based CORS allowing any *.up.railway.app origin. This makes PR environment testing work without manually setting FRONTEND_URL for each PR. Set ALLOW_RAILWAY_ORIGINS=true in Railway backend env vars. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
