Taken feature request from MM2026 planned features document:
Manual option to rebuild Artwork cache. This could be something a user runs overnight to freshen up the Artwork cache. It would also speed up browsing if users have lots of uncached Artworks.
It could be added to 'Edit tags / artwork' > 'Artwork' > 'Rebuild artwork cache'
submenu to the other mass artwork edit options already implemented in course of 0021575
