Pull Request Overview

This PR removes the rule squashing logic from the ACL manager, which previously attempted to optimize firewall rules by consolidating multiple per-peer rules into single wildcard rules when they covered all peers in the network.

• Removal of the squashAcceptRules method and its supporting logic
• Simplification of the applyPeerACLs method to use firewall rules directly from the network map
• Deletion of comprehensive test coverage for rule squashing scenarios
