Pull request overview

Fixes the cluster “Mirroring registry” settings page in Console v5 so the registry data renders correctly by switching the registry query to Suspense mode and adding a local loading fallback.

Changes:

• Wrap the mirroring registry settings content in a <Suspense> boundary with a spinner fallback.
• Enable suspense: true on useContainerRegistries to ensure the form initializes after data is available.
• Minor UI tweak: increase loader spinner size in cluster network settings.
