refactor(fields): Remove unused standard_fields method

    # variations.

    # Get all standard field constants

    end

    # @param field_value [String] The field value (e.g., "gl_user_id")

    # @return [String, nil] The constant name (e.g., "GL_USER_ID") or nil if not found

      # to identify and track usage of deprecated fields in the codebase.
