feat: integrate global metrics system into AHM scanner

- Add global metrics system to common crate for cross-module usage
- Integrate global metrics collection into AHM scanner operations
- Update ECStore to use common metrics system instead of local implementation
- Add chrono dependency to AHM crate for timestamp handling
- Re-export IlmAction from common metrics in ECStore lifecycle module
- Update scanner methods to use global metrics for cycle, disk, and volume scans
- Maintain backward compatibility with local metrics collector
- Fix clippy warnings and ensure proper code formatting

This change enables unified metrics collection across the entire RustFS system,
allowing better monitoring and observability of scanner operations.
