Fix storage display issues and use dynamic versioning

Phase 1 fixes for storage display:
- Replace findmnt with lsblk to eliminate bind mount issues (/nix/store)
- Add sudo to smartctl commands for permission access
- Fix NVMe SMART parsing for Temperature: and Percentage Used: fields
- Use dynamic version from CARGO_PKG_VERSION instead of hardcoded strings

Storage display should now show correct mount points and temperature/wear.
Status evaluation and notifications still need restoration in subsequent phases.
