Fix lsblk caching to properly parse SIZE and MOUNTPOINT

Split lsblk queries into two separate calls:
1. lsblk -dn for disk sizes (whole disk only, simpler parsing)
2. lsblk -rn for mount points (handles partition-to-parent mapping)

This fixes issues where:
- SIZE was empty due to delimiter confusion
- Mount points with spaces caused parsing errors
