Remove hardcoded pool mount point mappings for true auto-discovery

- Eliminate hardcoded mappings like 'root' -> '/' and 'steampool' -> '/mnt/steampool'
- Use device names directly for physical drives
- Rely on mount_point metrics from agent for actual mount paths
- Implement zero-configuration architecture as specified in CLAUDE.md
