Added FOCUS-46923 - Grades: If Co-Teacher Posts Grades, the Primary Teacher will be Removed from Teacher Completion

This update improves the behavior of the Grades Teacher Completion report. Previously, if grades were posted by a Co-Teacher, the Primary Teacher of the section would still appear on the report. With this update, if all grades for a section are posted, regardless of whether they were submitted by the Primary Teacher or the Co-Teacher, the teacher of record will no longer appear on the Grades Teacher Completion report. This enhancement provides administrators with a clearer and more accurate view of teachers who still need to post grades.
