Deploy console-app v0.10.12

[casey-brooks]

Summary

• Updates console_app_chart_version from 0.10.11 to 0.10.12 in stacks/platform/variables.tf.
• Leaves console_app_image_tag empty, so no temporary console image override is introduced.
• Does not modify unrelated platform versions.

Closes #573

Review complete. The change is limited to updating console_app_chart_version to 0.10.12, leaves console_app_image_tag empty, and matches the linked issue scope.

I verified Terraform formatting/initialization/validation locally. I could not run the exact helm/oras commands because those CLIs are not installed in this environment, but the corresponding GHCR chart and image manifests for 0.10.12 are present.
