[ew] Folder and file icons look too similar

the difference between a folder icon and the page icon is so small - the amount of time I click the wrong one is not funny. And yes - the nature has it that there always a page and folder with the same name next to each other - I’m quite sure we can solve this to reduce the wrong-clicks to 0

The issue names no files, tests, or entry points. Start by locating the folder and page icon definitions and their rendering path, then compare the icons where adjacent items share a name; done means the two icons are clearly distinguishable and wrong-clicks are reduced.
