chore: dependency cleanup (#1794)

- removed unnecessary smoothscroll-polyfill (electron is Chromium-only)
- removed deprecated mobx-react-devtools (can be used through browser extension)
- changed settings icon back to original (now called mdi-cog)
- removed electron-rebuild (handled by electron-builder install-app-deps)
