feat(api, web): enhance MikroTik integration and IP hit tracking

- Updated the `evofw-firewall.sh` script to improve the handling of NFT sets, ensuring compatibility with kernel limitations on counters and enhancing logging for better diagnostics.
- Introduced a new presence mode for MikroTik, allowing for real-time tracking of IP hits with updated last seen timestamps and packet counts.
- Enhanced the API to support the new presence mode, updating the database interactions to reflect the changes in how IP hits are recorded.
- Updated the agent detail view to display sync windows for MikroTik, providing clearer insights into blocked IPs and their activity.
- Improved documentation to reflect the new features and changes in the MikroTik handling process, ensuring clarity for users and developers.

These changes significantly enhance the monitoring capabilities and user experience for agents, particularly those using MikroTik devices.
