Michael Chus b9be93c213 Move NCCL interconnect and NVBandwidth tests to validate/stress ...

nvidia-interconnect (NCCL all_reduce_perf) and nvidia-bandwidth
(NVBandwidth) verify fabric connectivity and bandwidth — they are
not sustained burn loads. Move both from the Burn section to the
Validate section under the stress-mode toggle, alongside the other
DCGM diagnostic tests moved in the previous commit.

- Add sat-card-nvidia-interconnect and sat-card-nvidia-bandwidth
  validate cards (stress-only, all selected GPUs at once)
- Add runNvidiaFabricValidate() for all-GPU-at-once dispatch
- Add nvidiaAllGPUTargets handling in expandSATTarget/runAllSAT
- Remove Interconnect / Bandwidth card from Burn section
- Remove nvidia-interconnect and nvidia-bandwidth from runAllBurnTasks
  and the gpu/tools availability map
