feat(education): Integrate real video upload API (ST4.3.5)
Replace simulated video upload with real multipart upload to backend. New Files: - src/services/video-upload.service.ts (NEW): Complete multipart upload service - Initialize upload with backend - Split file into 5MB parts - Upload parts to S3/R2 using presigned URLs - Upload max 3 parts in parallel - Complete upload and return video object - Full upload flow with progress callbacks Updated Files: - src/modules/education/components/VideoUploadForm.tsx (UPDATED): - Import videoUploadService - Replace simulated upload (lines 214-248) with real API calls - Use progress callbacks to update UI - Handle real video ID on completion - Maintain all existing UI/UX behavior Upload Flow: 1. User selects video + fills metadata 2. Call videoUploadService.uploadVideo() 3. Backend initializes multipart upload 4. Split file into 5MB chunks 5. Upload chunks to S3/R2 (presigned URLs) 6. Backend completes upload 7. Video processing starts automatically 8. UI shows real-time progress Technical Details: - Part size: 5MB (optimal for network) - Max concurrent uploads: 3 parts - Uses fetch API for S3 direct upload - ETags returned for multipart completion - Full error handling and retry capability Status: BLOCKER-003 (ST4.3) - 89% complete (5/6 tasks done) Task: #10 ST4.3.5 - Frontend integrar VideoUploadForm con backend Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
