docs: integrate tsys2 hardware findings from Windows inventory

Browse Source 
tsys2 validated via PowerShell on Windows: 2 SSDs (Samsung 960 PRO
NVMe 512GB + Samsung 850 EVO SATA 1TB) -- the best local storage in
the fleet. wnode-tsys2 needs no NFS; boot on NVMe, bulk data on SATA
SSD. Both NICs are USB dongles (ASIX + Realtek) -- unavoidable on
this laptop form factor, no PCIe NIC expansion possible.

Updated storage tiers, wnode placement, and k8s labeling to reflect
that tsys2 is the fastest-storage worker node. Marked TODO.md items
as resolved.
