[FIX] website_sale: fix shop list view publish buttons

Publish buttons appeared in list view item in /shop with commit
5a5dd1e1.

They however never worked for some reasons:
* The publish buttons were unclickable as the around style was badly
implemented: the section title was over the publish button
* Even if it was clickable, the publish button handler had no prevent
default, thus it submitted the form it is in -> crash when no cart
button or added to cart on click on publish button if there was a cart
button...

Note: the style should be reviewed in next versions, this commit, as
a 9.0 fix, fixes the style with the minimum code and so that it does
not break any theme.
