Capture per-run IPMI power and GPU telemetry in power benchmark

- Sample IPMI loaded_w per single-card calibration and per ramp step
  instead of averaging over the entire Phase 2; top-level ServerPower
  uses the final (all-GPU) ramp step value
- Add ServerLoadedW/ServerDeltaW to NvidiaPowerBenchGPU and
  NvidiaPowerBenchStep so external tooling can compare wall power per
  phase without re-parsing logs
- Write gpu-metrics.csv/.html inside each single-XX/ and step-XX/
  subdir; aggregate all phases into a top-level gpu-metrics.csv/.html
- Write 00-nvidia-smi-q.log at the start of every power run
- Add Telemetry (p95 temp/power/fan/clock) to NvidiaPowerBenchGPU in
  result.json from the converged calibration attempt
- Power benchmark page: split "Achieved W" into Single-card W and
  Multi-GPU W (StablePowerLimitW); derate highlight and status color
  now reflect the final multi-GPU limit vs nominal
- Performance benchmark page: add Status column and per-GPU score
  color coding (green/yellow/red) based on gpu.Status and OverallStatus
