✨ feat(upload): add file upload user tracking and name parameter

- add fileName parameter to getUploadPolicy function for better file identification
- automatically record uploadUserId from authentication context when creating file records
- add uploadTime field to automatically record file upload timestamp
- remove uploadUserId from CreateFileDto as it's now set server-side from auth context
