Add ZIP bulk upload to asset manager

Features:
- Upload ZIP files with folder structure
- Automatic extraction and MD5/SHA256 calculation
- Preserve folder paths as EA CDN paths
- Auto-categorize based on file extensions
- Update existing assets automatically
- Bootstrap tabs for single/bulk upload UI
- Progress feedback (X new, Y updated)

Example: cars/porsche.dat → /cars/porsche.dat
