More explicit icons in modal to set or edit the label associated with an alert

Thanks to #77, it is possible to set or edit the label associated with an alert !

The code is perfectly functional, but in my opinion, the icons are not clear enough for users. See screenshot below.

Specifically, the icon label ‘other smoke’ is not satisfying. We would like to see a source of smoke and a smoke.

We would be delighted to receive a suggestion for a more explicit icons or a suitable logo design.

Happy to discuss it !
