feat: integrate multi-cloud storage (S3, OSS, COS, Local)

Browse Source 
Add built-in storage support from v-hono-storage module:
- StorageProvider interface with 4 backends
- FileService with HTTP handlers
- Multipart upload support
- 86 property-based tests
- Retry mechanism with exponential backoff

Breaking: None (backward compatible)
