feat: Add full support for Xiaomi Purifier Elite (zhimi.airp.meb1)

- Implemented unique features for Xiaomi Purifier Elite:
- Added specific mappings for zhimi.airp.meb1.
- Updated status output to include PM10 and other key metrics.
- Enhanced logging for device debugging.

This resolves issue #1902 on GitHub.
