docs(prod): fill in node-2 inventory; drop stale investigate bullets

Browse Source 
Records node 2's as-found hardware alongside node 1 and removes two bullets that my earlier
edit left duplicated/obsolete (the BIOS comparison is done; clear-CMOS was listed twice).

Makes the hardware ASYMMETRY explicit in the table rather than buried in prose: node 1 is a
~2011 Micron C400 SATA SSD at 69% life with 15 grown bad blocks and 187 erase failures; node 2
is a Samsung PM9A1 NVMe at 96% life, PASSED. Same chassis, same BIOS, same CPU, same partition
layout — very different storage. §2 requires an identical disk layout across all three nodes
because Longhorn replica placement assumes symmetry, so this belongs in the inventory where the
disk decision will be made.

Serves: R-ENV-03. Task: T-7.1.

**The nodes are NOT hardware-symmetric.** Node 1 has a ~2011 SATA SSD with real wear; node 2 has a
healthy modern NVMe. §2 requires an identical disk layout across all three because Longhorn replica
placement assumes symmetry — so this is a live input to the disk decision, not a footnote. Node 2's
NVMe is the drive node 1 should have had.
Dev nodes for comparison: 8 vCPU / 24 GiB / Debian 13, **two** dedicated data disks (Longhorn + etcd).

- [ ] **Set `After Power Loss=Power On`** regardless of the memory question — §1 requires it and
node 2 currently violates it.
- [ ] Clear CMOS / load setup defaults on node 2 to force a full memory retrain, then re-check.
- [ ] Compare node 2's BIOS settings against node 1 directly. Look for a memory remap / "Above 4G
decoding" style option, and for any memory-limit or 32-bit-addressing setting.
- [ ] Clear CMOS / load setup defaults on node 2, then re-check `MemTotal`.
- [ ] Reseat the DIMM; try it in DIMM3; try it in node 1 (swap test) — that isolates DIMM vs slot
vs board in one move.
- [ ] `memtest86+` if the above do not resolve it.
