Chore/mini grid design fixes

Fixes #4274

Mini design fixes for the Grid Panels system

Commit Details:

• Panel reorder: Re-enabled the logic that only shows a dropline if dropping the panel there would result in a layout change
• Panel reorder: the area above the canvas is a drop target now so you can easily reorder panels to the other side of the editor
• The code editor has a somewhat nicer title bar made by Malte last friday
• The code editor title bar's minimize and maximize buttons are wired in:
  • Minimize moves it below the Navigator
  • Maximize move it to be the leftmost panel
• A fix of an accidental mutation in an update function
• The panel layout's padding around the window border is significantly reduced to 8px
• Hiding that weird little square thumbnail that would travel with the reordered panels :)

Extracting out the existing value into a variable would probably make this a little cleaner.
