This commit introduces a robust TIMED project mode for code assessments, featuring countdown timers and an integrated proctoring engine to monitor tab switching, fullscreen usage, and activity. Students can now participate in formal, anti-cheat monitored exams, while teachers gain dedicated grading interfaces, automated marks computation, and results publication workflows. These changes significantly level up the platform for secure, high-stakes coding evaluations. Assessment Mode
