feat(firewall): add packet statistics tracking for firewall clients

Enhanced the firewall client functionality by introducing packet statistics tracking, including the cumulative count of packets dropped and accepted. Updated the API to support these new fields and modified the database schema accordingly. Improved the firewall scripts to collect and report packet statistics, ensuring better visibility into client performance. Adjusted the UI components to display packet counts in the clients table, enhancing user experience and monitoring capabilities.
