fix #10640: the interface fails to be queried，/v1/graphql

[david-ourlegup]

The schema registry notification color hook has been updated to improve performance. A check was added to skip API calls if running in CE mode or if the schema registry host is not configured. This change also includes a modification that skips the query completely when the schema registry is unavailable, and returns a loading state instead. These enhancements aim to optimize resource usage and provide better user experience.

Thanks @david-ourlegup for submitting this PR to improve the schema registry notification color hook! These optimizations look very useful - particularly skipping API calls in CE mode and when the schema registry host isn't configured, and the improved handling when the registry is unavailable.
We'll test these changes and review the code. If everything looks good, we'll merge this and include it in our next release.
Appreciate your contribution to improving performance and UX!
