Fix HDD/SSD detection to be more accurate

Improved device type detection:
- Use anchored regex (^Rotation Rate:) to avoid false matches
- Check for actual RPM values (e.g., "7200 rpm") to confirm HDD
- Only match SSD in model name field, not anywhere in output
- Default to HDD when Rotation Rate field is missing

This fixes drives like WDC WD80EFZZ being incorrectly detected
as SSDs when the Rotation Rate field wasn't being matched.
