chore: bump controller image to d122d39 (OTel semconv fix) (#102)

Picks up the OTel schema-URL fix from #101, which unblocks the post-#99
controller image. Prior image (20a1a90) crashes at startup with:

  Failed to initialize OTel MeterProvider
  conflicting Schema URL: ...1.40.0 and ...1.26.0

  sha256:6a0a11bd2b135777d7bf4973f4009553b49a3cd4d2bfe41e08947e6a1780fde4

Post-Flux-sync verification:
  kubectl -n sei-k8s-controller-system get pods
  # expect: all pods Running on the new image, no CrashLoopBackOff

Unblocks autobake workflow (platform#101) which reads
status.internalService.name from the post-#99 controller.
