Implement designs for event teaser/listing page within Olivero

I sincerely apologise for writing CSS -- desperate times, etc etc. There was some grid weirdness, the grid-column style was not applying for anonymous users, and I reduced the gap as well to match the designs.

There is still way too much space between the title and the view, but I think we can tackle that separately as it's a global issue.

Oh come on...you barely wrote any CSS. I was expecting an entire inscrutable style sheet. Didn't even get that!

I agree - we need to start landing these, desperate times and such. Better to do it with some rough edges we can smooth out later than not do it at all.

Merged into 1.x. Thanks!
