[Feature Request]: Clear appdata

[Bartek200219]

Preflight checklist

• [X] I have searched the issue tracker for a bug report that matches the one I want to file, without success.
• [X] I have searched the features list for this feature, and I couldn't find it.
• [X] I have checked that I'm using the latest stable version of the app.

Problem Description

After series of updates Miru stop behaving correctly like Not playing/searching torrents and some anilist error popups, so i had to delete appdata folder. It happend to me twice over half a year of usage.

Proposed Solution

Below restore defaults should be a button to clear all of appdata.

this is a bad hack for an unspecified issue, report the individual issues not just "wah no worked"
