Display mount points instead of pool names in storage section

- Add mount_point field to StoragePool struct
- Create mapping from pool names to mount points
- Update display to show user-friendly mount points (/, /mnt/steampool)
- Keep device detection for SMART data (temperature, wear)
- Resolves disk name confusion on different hosts
