Fix GPU inventory: exclude BMC virtual VGA, show real NVIDIA model names

Two issues:
1. BMC/management VGA chips (e.g. Huawei iBMC Hi171x, ASPEED) were included
   in GPU inventory because shouldIncludePCIeDevice only checked the PCI class,
   not the device name. Added a name-based filter for known BMC/management
   patterns when the class is VGA/display/3d.

2. New NVIDIA GPUs (e.g. RTX PRO 6000 Blackwell, device ID 2bb5) showed as
   "Device 2bb5" because lspci's database lags behind. Added "name" to the
   nvidia-smi query and use it to override dev.Model during enrichment.
