Align page edit features in Site Editor and Post Editor

[jameskoster]

There are a number of smaller edit actions that are available in the post editor, but not the site editor. The mis-alignment means users sometimes need to hop between editors, which can be frustrating.

In addition to the Page Inspector, we should consider the new details panel, and the Command Palette when working out the placement for these items.
