fix(exporter): preserve all HGX GPUs with generic PCIe slot name

Browse Source 
Supermicro HGX BMC reports all 8 B200 GPU PCIe devices with Name
"PCIe Device" — a generic label shared by every GPU, not a unique
hardware position. pcieDedupKey used slot as the primary key, so all
8 GPUs collapsed to one entry in the UI (the first, serial 1654925165720).

Add isGenericPCIeSlotName to detect non-positional slot labels and fall
through to serial/BDF for dedup instead, preserving each GPU separately.
Positional slots (#GPU0, SLOT-NIC1, etc.) continue to use slot-first dedup.
