full screen mode implementation for dashboard (#12265)

* full screen mode implementation

* Have Edit and Add buttons kick you out of full screen mode

* Instruct the grid to resize when switching between full screen and regular modes

* Use new styles and listen for ESC key

* handle dark theme

* Remove full screen option from edit mode

It’s awkward with no obvious save button to escape edit mode.

* Code review comments

* deregister the route handler if the user navigates away from the dashboard page.

* Use a new broadcast event rather than hijacking the window resize one
