feat: add OpenList upload support and upload tasks monitoring page

Backend:
- Add OpenListRecordArtifactUploader implementing AList-compatible API upload
- Add Uploading status to RecordArtifactUploadStatus enum
- Add MarkUploadStarted() to RecordResult entity for upload progress tracking
- Add ListUploadStatus API endpoint with pagination and status filtering
- Add UploadTaskItemDto and UploadTaskListResponse models
- Add upload segment count stats (uploaded/failed/uploading) to session DTO
- Add OpenListUploadSettingsDto and upload target type OpenList

Frontend:
- Add UploadTasksView page with route /upload-tasks
- Add upload status labels and UploadTaskItem types
- Refactor MainLayout navigation and clean up main.css
- Polish DashboardView, MetricCard, StatusBadge, RightDrawer components
- Update SettingsView to support OpenList upload configuration

Build:
- Add frontend/Dockerfile.arm64 for ARM64 frontend image
- Update build-arm64-image.sh script

Other:
- Add segment_completed_openlist.sh trigger script
- Add prototype/ directory with UI mockups
- Add frontend .dockerignore refinements
