iOS PWA icon not visible #4766

on iOS 17.7.1 Safari, the PWA icon for Tangled is invisible, probably because the file accessed, /logos/dolly.png (via <link rel="apple-touch-icon" href="/logos/dolly.png" /> in web/src/app.html) is black on transparent, and my iPhone uses black for the transparent background.

the solution is simple: add a white background to the PNG, if you intend for the iOS PWA icon to be black-on-white, or add a black background to the PNG and make Dolly white if you intend for it to be white-on-black (personally think this looks better 😃 ).

i can't make a PR for this because it seems like the entire web/static/logos/ directory has been git-ignored by web/static/.gitignore.
