feat: processing flow enhancement + responsive UI
Phase 2 - Processing flow:
- Multi-task monitoring: store supports concurrent task tracking
- Task retry: POST /api/tasks/{id}/retry re-runs failed tasks
- Dashboard multi-task cards with progress, error details, retry/dismiss
- Log panel expanded from 10 to 50 lines with "view all" link
Phase 3 - UI/UX:
- Mobile sidebar drawer (< 768px) with hamburger menu
- Layout responsive styles (768px, 480px breakpoints)
- Tasks/Logs pages responsive (stat cards, filters, columns)
- File views responsive (header wrap, button sizing)
