Add a SnackBar to show HTMx errors 

We do not have any design yet for errors and other notifications, so i
followed material design, for now, since we already kind of use their
input fields design.

This time i decided to use AlpineJS because there is not that much HTML
code, and the transitioning is way easier to do in AlpineJS than it
would be with plain JavaScript—not to mention the bugs i would
introduce.
