Add a clean cache option to safely delete build files

It would be nice if we could add an option on the dashboard to safely delete the cached build files to free up space

If I am low on disk space, I can easily free up disk space

There is a button in the 3 dot menu on each card to Clean Build Files. Is that not what you are requesting?

Hi, thanks I didn't notice this option before.

I cleaned all my build files using the above and used space went from 9.5GB to 7.7GB.

root@esphome:/config/.esphome# du -skh *
122M	build
276K	idedata
7.7G	platformio
48K	storage

root@esphome:/config/.esphome/platformio# du -skh *
1.3G	cache
6.5G	packages
12M	platforms

There is still a lot of space in use, I think it would be nice to add an option to clean all build files and clean all cache maybe?
