feat(analytics): add Rybbit proxy rewrites and env vars

- Add Next.js rewrites to proxy /api/script.js and /api/track through self-hosted Rybbit
- This bypasses ad blockers that would block rybbit.nodecrew.me directly
- Add NEXT_PUBLIC_RYBBIT_HOST and NEXT_PUBLIC_RYBBIT_SITE_ID env vars to K8s deployment

k8s/deployment.yaml
