Node position to compose (#877)

* Move battery info to compose - always show voltage level and icons to match battery percentage
Use tool text in preview, rather than actually set text value
Simplify node info layout to avoid defining margins on everything

* Move node position to Compose

* Update hyperlink color to match previous value

* Use compose preview in layout editor

* Use compose preview in layout editor

* Add simple preview for use in layout
