Summary

Log warnings when nvsandboxutils or NVML dGPU discoverer initialization fails, for both full GPU and MIG devices. The warning names the failing backend and includes the original error, while the existing fallback and joined-error behavior stays intact.

Fixes #2114.

Tests

  • Added regression tests for all four warning paths (confirmed failing before the fix).
  • make build, make fmt, and make test passed in a Linux Go container.
