Default pen stroke width needs to be thicker

Traditionally, “white boarding” involves using very thick pens. Why? Thick pens allow us to fill space quickly, and illustrate big-picture ideas rather than getting bogged down in precise details.

The default pen stroke in FigJam is too thin. We should make the default more like an Expo marker. Even the thicker option currently is still too thin.

Obviously you can zoom in on the board, but then the sticky notes get too large.
