Toast when copying address to clipboard

Apparently it is not a standard feature for the toast to appear when we copy to clipboard, so we need to implement this ourselves.

Capacitor has a native "toast" plugin. We should look into that, but also DaisyUI has "toast" components too if we want to homebrew the styles.

Need to test on both old and new phones regardless of the option we choose to make sure it doesn't interfere with the standard toast that DOES appear on newer Androids.

Not sure what the default behavior is on iOS.
