fix: PROPFIND file size fallback for old files and use real upload timestamp

Browse Source 
- File size: prefer FileSizeBytes, fall back to FileSize (MB) * 1024^2
  for files uploaded before FileSizeBytes was added
- Timestamps: use TimeStamp from metadata instead of current time,
  so clients show the actual upload date, not the PROPFIND request time
