Add wear percentage display and NVMe temperature collection

- Display wear percentage in storage headers for single physical drives
- Remove redundant drive type indicators, show wear data instead
- Fix wear metric parsing for physical drives (underscore count issue)
- Add NVMe temperature parsing support (Temperature: format)
- Add raw metrics debugging functionality for troubleshooting
- Clean up physical drive display to remove redundant information
