Use ANNOTATION_TYPE in OnPropertyPrefixCondition

Add a static ANNOTATION_TYPE constant for ConditionalOnPropertyPrefix and use it when reading annotation attributes and creating ResolvablePlaceholderAnnotationAttributes. This replaces direct references to ConditionalOnPropertyPrefix.class/its name, reducing duplication and improving maintainability.
