Show NVMe drives with bay mappings in main table

NVMe drives mapped to m2-1, m2-2 slots now appear in the main drive
table with their bay position, instead of in a separate unmapped
section.

- Extended bay loop to include m2-* slots after numeric bays
- NVMe section now only shows truly unmapped NVMe drives
- Mapped NVMe drives show full SMART data like other drives

Fixes: #5
