Dense joplin page list view

### As a [user type] I want [capability] so that [benefit].

**Is your feature request related to a problem? Please describe.**
Emerging feedback from user testing (n=1) the publish queue was that they wanted a denser list view of pages. They thought the various "mini buttons" below page titles, and the generous whitespace were hiding content below-the-fold.

**Describe the solution you'd like**
We could try a few things:
- Remove unnecessary buttons: the `edit` button is redundant to the page title link, which both lead the author to the same place
- Make the mini-buttons visible on hover. This would technically "hide them" from the default view, but they would only be surfaced when the user needed them and otherwise out of the way.
- Google docs solution: kebab menu at the far right
- Reduce whitespace
- Reduce the number of columns in the list view, and perhaps modify how and where those attributes are presented
