feat(firewall): enhance blocklist handling and installation script

Updated the firewall scripts to improve blocklist handling by introducing a new method for fetching and parsing blocklist data using either `jq` or `python3`. Enhanced the installation script to ensure the presence of required dependencies and provided user guidance for post-approval actions. Additionally, improved logging for applied prefixes and total counts, ensuring better visibility into the firewall's operational status.
