* Tweaked log messaging for library scan when no files were scanned.
* When a theme that is set gets removed due to a scan, inform the user to refresh.
* Fixed a typo and make Darkness -> Brightness
* Make download theme files allowed to be invoked by non-authenticated users, to allow new users to get the default theme.
* Hide all series side nav item if there are no libraries exposed to the user
* Fixed an API for Tachiyomi when syncing progress
* Fixed dashboard not responding to Series Removed and Added events.
Ensure we send SeriesRemoved events when they are deleted.
* Reverted Hangfire SQLite due to aborted jobs being resumed, when they shouldnt. Fixed some scan loop issues where cover gen wouldn't be invoked always on new libraries.
