redirect Squid access logs to stdout (#888)

## Summary

This PR modifies the Squid proxy configuration to redirect access logs to standard output instead of writing to a file within the container.

## Changes

- Changed `access_log` configuration from `stdio:/var/log/squid/access.log` to `stdio:/dev/stdout`
- Applied to both egress and ingress proxy configurations in `pkg/container/docker/squid.go`

## Benefits

- Access logs are now properly captured by container logging systems
- Logs are accessible through standard Docker/Podman log commands
- Better integration with container orchestration platforms
- Follows container best practices for logging
