Improve NVMe serial parsing and restructure MergerFS display

- Fix NVMe serial number parsing to handle whitespace variations
- Move mount point to MergerFS header, remove drive count
- Restructure data drives to same level as parity with Data_1, Data_2 labels
- Remove "Total:" label from pool usage line
- Update parity to use closing tree symbol as last item
