[CI] Migrate all gpu_1_queue jobs to h200_18gb MIG

Move all test steps that were falling through to gpu_1_queue (L4)
to explicitly use device: h200_18gb (H200 18GB MIG partition).

This covers 53 steps across 15 test area files including kernels,
entrypoints, models, pytorch compilation, quantization, and more.
