Provide a way or a widget to select a previously uploaded file (i.e. files already on the server)

[bhch]

This will be useful in cases where there are dedicated apps for managing media files or to avoid re-uploading files.

A user will click on the file input, but a modal will open, then a request will be sent to the server and the server will return a list of all the available files for selecting. The user can then choose a file. The path of the file will be saved in the JSON data.
