[FIX] util/report: improve report categories for better precision

Summary:
This update improves the handling of report categories in the utility module
to ensure they are more precise and well-organized.

Reason for the Change:
It was observed that the report categories were not sorted lexicographically in
order, leading to a lack of precision and organization. To address this,
the categories have been sorted lexicographically to enhance their
clarity and structure.
