Marks grid, absences & export

The marks grid (plan → Marks) shows every roster student × subject:

• Final score once marked; submitted for auto-scored papers awaiting finals; in progress for live attempts.
• Absent — hover an empty cell and flag the no-show; it lands in the grid and the CSV.
• Export — downloads a class-wise marks CSV (raw scores).

The Reports page adds the per-plan funnel: roster → attempts → submitted → marked.
