refactor(agent): remove goutils/server dependency and use direct HTTP server setup

- Replaced `goutils/server` helper library with manual HTTP server configuration for agent socketproxy
- Removed entire `agent/pkg/server/server.go` package (43 lines) that wrapped TLS/HTTP server functionality
- Added explicit TCP listener and integrated zerolog with server's error logging
- Cleaned up 17 unused indirect agent dependencies
