feat: Add CrowdSec management endpoints and feature flags handler

- Implemented CrowdSec process management with start, stop, and status endpoints.
- Added import functionality for CrowdSec configuration files with backup support.
- Introduced a new FeatureFlagsHandler to manage feature flags with database and environment variable fallback.
- Created tests for CrowdSec handler and feature flags handler.
- Updated routes to include new feature flags and CrowdSec management endpoints.
- Enhanced import handler with better error logging and diagnostics.
- Added frontend API calls for CrowdSec management and feature flags.
- Updated SystemSettings page to manage feature flags and CrowdSec controls.
- Refactored logs and other components for improved functionality and UI consistency.
