Three Foxes (in a Trenchcoat) 99911fbb3a fix: use proper JSON marshaling for customrest prompt to handle special characters (#1615 )

This fixes issue #1556 where the customrest backend fails when error messages
contain quotes or other special characters.

The root cause was that fmt.Sprintf was used to construct JSON, which doesn't
escape special characters like quotes, newlines, or tabs. When Kubernetes error
messages contain image names with quotes (e.g., "nginx:1.a.b.c"), the resulting
JSON was malformed and failed to parse.

The fix uses json.Marshal to properly construct the JSON payload, which
automatically handles all special character escaping according to JSON spec.

Fixes #1556
