Add server-side per-problem video recording that allows teachers to click on completed problems in the observer progress indicator to watch recorded videos of each problem attempt. Key changes: - New vision_problem_videos schema and migration for per-problem videos - VisionRecorder refactored for per-problem frame management - Socket server triggers ffmpeg encoding on problem transitions - API routes for streaming videos and listing available recordings - SessionObserverModal enables browse mode on progress indicator - ProblemVideoPlayer component for viewing past problem recordings Each problem gets its own MP4 video encoded incrementally as it completes, making playback immediately available for recently completed problems.
