Remember last audiobook used while importing library for quick selection

[T4g1]

Summary

While importing files from a library, the scan feature can miss some matches. Searching them manualy again and fixing the search query is tedious so the modal now remembers the last one that was used and the user can directly use it instead

Also, in the audiobook details view: When looking at the files, they are displayed in the same technical order from the DB. This can be random so I added a sort function to display them by filename

Before:

After (not the same instance but you get the idea):

Changes

Testing

This was manualy tested as the change is only on the frontend
