text: Title: Use original filename when saving photos or videos
  Body: **Describe the enhancement you'd like**
  Saving a file should give it its original filename instead of the hash
  
  **Describe why this will benefit the LibrePhotos**
  Being able to save an image with its original filename is better in every way.
  
  Saving e.g. `http://localhost:3000/media/photos/316f2524acd7f5841c924fe4f1a422641` should use `IMG_2024_0101_1234.jpg` instead of `316f2524acd7f5841c924fe4f1a422641.jpg`
  
  All that is needed is an additional HTTP header:
  `Content-Disposition: inline; filename="IMG_2024_0101_1234.jpg"`
  **inline** so it preserves the possibility to view the image in the browser, and at the same time you can save it with its real filename.
