fix(navbar): logo on a stored light bar follows the link text in the editor

Legacy Navbar nodes store backgroundColor '#ffffff' + textColor '#3f3f46'; the
editor took the logo colour from the Site Design text (light on a dark design)
while the export already uses logoColor || textCol. Same dark-palette class as
finding 8.
