docs: integrate tsys2 hardware findings from Windows inventory

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.

+### STATUS: Collected 2026-07-27
+
+**Disk inventory — RESOLVED:**
+- Disk 0: Samsung SSD 960 PRO **512 GB NVMe** (best local storage in fleet)
+- Disk 1: Samsung SSD 850 EVO **1 TB SATA SSD**
+- Both SSDs, no spinning rust. 1.5 TB total local SSD.
+
+**Network adapters — RESOLVED (concerning):**
+- StorageNetwork: **ASIX USB to Gigabit Ethernet** (dongle, D4-81-D7-3E-0D-5E)
+- Ethernet: **Realtek USB GbE Family Controller** (also USB, 18-FD-CB-00-D2-CA)
+- Wi-Fi: Intel 8265 (disconnected)
+- **Both wired NICs are USB-attached.** Same anti-pattern as tsys4/9.
+  Unavoidable on this laptop form factor — no onboard PCIe NIC available.
+
+**GPU — RESOLVED:**
+- Intel HD Graphics 630 (integrated, 1 GB)
+- NVIDIA Quadro M1200 (4 GB, confirmed for passthrough)
+
+**PCIe slots — RESOLVED:**
+- Slots 3/6/7/8 report "Available" but these are laptop M.2/WWAN slots, not
+  user-accessible full PCIe. **Cannot add a PCIe NIC.** NVMe slot occupied
+  by 960 PRO.
+
+**RAM — PARTIAL:**
+- Total 32 GB confirmed (34,097,573,888 bytes).
+- Per-stick detail failed to run (PowerShell line-break split
+  `Format-T` + `able`). Re-run the command below if bandwidth planning
+  needs stick-level detail:
+  ```powershell
+  Get-CimInstance Win32_PhysicalMemory | Select-Object Manufacturer, PartNumber, Capacity, Speed, ConfiguredClockSpeed, DeviceLocator, FormFactor | Format-Table -AutoSize
+  ```
+
+**Service tag — CONFIRMED:** `GH1XZG2` (Precision 5520).
