mobile: iOS-style widget + animations, 2-click desktop icons, new wallpapers

Mobile:
- iOS-style open/close animation for app views (grows from the tapped icon,
  always slides straight down out of view and shrinks on close)
- digital 2x1 clock widget in an iOS-style frosted-glass panel
- new phone wallpaper (phonewallpaper.jpg)
- larger notch

Desktop:
- desktop icons and shortcuts now launch on the second click
- open/close/launcher animations
- windows keep their state when toggling Gruvbox/Desktop themes, and the
  Welcome window only appears on the first page load

Other:
- update wallpaper credits to wallpapercave
- allow LAN hosts in dev (allowedDevOrigins) so phones can load the dev
  bundle instead of getting a 403 and an inert page
