feat(nginx): add integrations endpoint with CORS support

Add new /integrations/ location block that proxies requests to
integrations-openreplay:8080 service. Includes proper CORS headers
for cross-origin requests and WebSocket upgrade support.

- Rewrite /integrations/ path to root
- Configure proxy headers for forwarding
- Set connection timeouts for stability
- Add CORS headers for API access
