feat(extend-http-xmlpath): add system info metric and improve XML parsing

- Add new metric 'system_info' to collect device information
- Update 'status' metric to use more accurate XML path
- Introduce aliasFields and calculates sections for better data handling- Improve field naming consistency across languages
