feat: NVIDIA GPU temperature support (thermalGpu widget)
Adds GPU detection via nvidia-smi during install, injects per-GPU temps into
$res->{sensorsOutput} from a Perl block in Nodes.pm, and adds a thermalGpu
ExtJS widget that renders 'GPU Thermal State' on the node summary page.
Format: each GPU appears as 'GPU<idx> <model>' under the sensors JSON with
{Adapter: 'NVIDIA', GPU Core: {temp1_input: <celsius>}}. Widget filters keys
starting with 'GPU', sorts, and prints temps with a color threshold (yellow
≥85°C, red ≥95°C). Skips host gracefully if nvidia-smi is missing.
Tested on Proxmox 9 with 2x RTX 3090.
