refactor(benchmark): replace whoami service with bench server

- Updated dev.compose.yml to define a new bench service that serves 4096 bytes of random data.
- Modified configurations for Traefik, Caddy, and Nginx to route traffic to the new bench service.
- Added Dockerfile and Go application for the bench server, including necessary Go modules.
- Updated benchmark script to target the new bench service endpoint.
