Implement CrowdSec integration with API endpoints for managing IP bans and decisions

- Added unit tests for CrowdSec handler, including listing, banning, and unbanning IPs.
- Implemented mock command executor for testing command execution.
- Created tests for various scenarios including successful operations, error handling, and invalid inputs.
- Developed CrowdSec configuration tests to ensure proper handler setup and JSON output.
- Documented security features and identified gaps in CrowdSec, WAF, and Rate Limiting implementations.
- Established acceptance criteria for feature completeness and outlined implementation phases for future work.
