feat: frontend Sentry integration + auth error handling

- Add sentry.client.config.ts and sentry.server.config.ts
- Add @sentry/nextjs to package.json
- Replace TODO:SENTRY in ErrorBoundary with actual Sentry.captureException
- Add console.error + Sentry reporting in auth.ts authorize and refreshAccessToken
- Enable TypeScript strict checks in production builds only
