accessibility: samigo: Color is the only method of indicating a quiz is available late - needs text/non-visual indicator.

When an assessment is available for a late submission, the Due Date displays for the student in red text. This is the sole indicator that the assessment is available late, and may not be available to colorblind or visually-impaired students. A text indicator is needed for these quizzes.

Suggested fix: Add the word (late) after the date in the Due Date column for assessments allowing a late submission.
