[Feature] Clear cache button to removed deleted files from files tab.

[madmax2]

Is your feature request related to a problem? Please describe.

There is an ongoing issue with Nut (including version 3.3) where the deleted files are not removed from files tab
after doing a scan.

It has been mention here

[Bug] Scanning does not remove deleted files from files.json
#297

Describe the solution you'd like

The best solution is to add a clear cache or refresh button that deletes the files.json file
and then automatically does a scan to refresh the current files tab.

Describe alternatives you've considered

Need to manually delete the files.json file but this is not as good as a clear cache button as suggested

Did you ever figure out a way to clear the list?
