fix: dedup GPUs across multiple chassis PCIeDevice trees in Redfish collector

Supermicro HGX exposes each GPU under both Chassis/1/PCIeDevices and a
dedicated Chassis/HGX_GPU_SXM_N/PCIeDevices. gpuDocDedupKey was keying
by @odata.id path, so identical GPUs with the same serial were not
deduplicated across sources. Now stable identifiers (serial → BDF →
slot+model) take priority over path.

Also includes Inspur parser improvements: NVMe model/serial enrichment
from devicefrusdr.log and audit.log, RAID drive slot normalization to
BP notation, PSU slot normalization, BMC/CPLD/VR firmware from RESTful
version info section, and parser version bump to 1.8.
