[Feature Request] Integration of AbuseIPDB API for enhanced connection filtering

🚀 Feature Request

BotSentry is already a powerful tool for server protection. However, many malicious IPs are already documented in global databases like AbuseIPDB. Currently, we rely on local detection, but we could improve efficiency by checking incoming connections against established abuse reports before they even attempt to join.

I would like to propose adding an AbuseIPDB API check integration. This would allow BotSentry to query the AbuseIPDB database for an IP's "Abuse Confidence Score."

Key details:

• Config Toggle: A configuration value to enable/disable the API check (e.g., enabled: true/false).
• API Key: A setting to provide the user's AbuseIPDB API key.
• Threshold: A configurable value for the minimum confidence score required to trigger a block (e.g., block if score is > 80%).
• Caching: (Optional) Caching results locally for a certain period to minimize API calls.

Additional context
AbuseIPDB is a industry-standard tool used worldwide. It is especially popular among hosting providers in Germany, the UK, and the USA to list IPs involved in DDoS attacks, botnets, and other malicious activities. Integrating this would put BotSentry on par with high-end enterprise filtering solutions.

The issue names no repository files, tests, or entry points. Start by locating the configuration and incoming-connection filtering paths, then review AbuseIPDB's API requirements and the proposed toggle, key, threshold, and caching behavior. Done means the integration's scope and configuration are implemented and its filtering behavior is verified.
