Update notes title to reflect history too
Move notes forms to modals

* The notes forms aren’t used as often as the history and notes view,
the forms get in the way.
* Use the same modal mechanism as the workflow buttons to add edition
notes and important notes. (Note that this doesn’t work without
Javascript, but you can’t currently get to this tab if Javascript is
disabled)
* Move preview and factcheck details to beneath tab title
* Add primary-styled buttons to open note modals
