`cursor: pointer` when hover

[Jonsonmon]

I think adding cursor: pointer to the .header or .title-card-header etc (depends if title-card-clickable is true/false) can be great for Browsers. (native)
Did some tests, this should also be added:

* {
  -webkit-tap-highlight-color: transparent !important;
}

For the bleeding issue...
BTW, I think <ha-ripple> can be also great for the new "hover" cursor.

Please let me know if you need more details :)
