Fix pulse_test: run all GPUs simultaneously, not per-GPU

Browse Source 
pulse_test is a PSU/power-delivery test, not a per-GPU compute test.
Its purpose is to synchronously pulse all GPUs between idle and full
load to create worst-case transient spikes on the power supply.
Running it one GPU at a time would produce a fraction of the PSU load
and miss any PSU-level failures.

- Move nvidia-pulse from nvidiaPerGPUTargets to nvidiaAllGPUTargets
  (same dispatch path as NCCL and NVBandwidth)
- Change card onclick to runNvidiaFabricValidate (all selected GPUs at once)
- Update card title to "NVIDIA PSU Pulse Test" and description to
  explain why synchronous multi-GPU execution is required
