Super duper Studio canvas update

The Studio canvas has some work left to be done to match the Figma design I did a year ago. Some functionalities in the design are really helping with UX, like circle color and line type.

Items are better alighted than now and attributes have ellipses when to long.

The forwards were hard to draw. So ignore the line shape (and missing label)
