fix: Enhances user grade selection and display

Adds a custom user selector class to streamline user search
and selection based on name or email.

Improves grade display by showing the final grade and maximum
possible grade, enhancing clarity for end-users.

Includes new language strings for improved user interface
text clarity during user selection and grade reporting.

Updates the plugin version to reflect substantive changes.
