Rework the /topo diagram from side-by-side stacked cards into one tall
vertical bar per CPU socket with everything attached to it branching off
sideways (socket 0 left/branches right, socket 1 right/branches left).
Disks are now parented under the storage controller they physically hang
off (SATA/AHCI, SAS HBA, RAID) — itself a NUMA-affine PCIe device under one
socket — instead of a synthetic catch-all node. The disk->controller link
is read from a new storage-controllers.txt techdump
(platform.StorageControllerMapScript, a /sys/block walk); disks with no
resolvable controller fall back to an "Other" bar. No board/root node.
