feat: integrate Sentry + fix CI/CD issues

Sentry Integration (補強 SignOz):
- Add @sentry/nextjs for frontend error tracking + session replay
- Add sentry-sdk[fastapi] for backend error tracking
- Create sentry.client/server/edge.config.ts
- Integrate with next.config.js + instrumentation.ts
- Add Sentry exception capture in FastAPI error handler
- Create deployment scripts for Self-Hosted @ 192.168.0.110

CI/CD Fixes:

- Add NEXT_PUBLIC_API_URL env var to CI build step
- Add build-arg to Docker build verification

E2E Test Improvements:
