Replace the reverted Sentry integration with PostHog for client-side error tracking, automatic exception capture, session replay, and pageview tracking. Add X-Request-Id header to API requests for cross-service correlation with Backend-Service Sentry traces. - posthog-js with capture_exceptions for window.onerror/unhandledrejection - PostHogProvider wrapping the component tree with pageview tracking - global-error.tsx error boundary capturing render errors to PostHog - RTK Query error middleware reporting API failures to PostHog - X-Request-Id (crypto.randomUUID) on every backend API request - productionBrowserSourceMaps for stack trace resolution
