Designed default app icons & appstore visuals

[0x70b1a5]

Problem

• change the "color dot" icons to deterministically show one of the designer's preset stock icons, on homepage and in appstore
• appstore download/install/launch buttons are now all different colors to better show change of state in ui
• appstore shows all apps on main page, paginated, and featured apps as chosen by Kinode
• remove "ratings" from app page until feature is done
• use the 🚫 mouse cursor for unclickable app icons

Testing

• verify that system apps on homepage "all apps" have a designed icon and a 🚫 cursor if no web ui exists for it
• verify that you can search for apps on the appstore
• verify all listed apps show up in a scrollable view on the main appstore page
• verify ratings aren't shown on app pages anymore
• download an app with a ui. verify that the buttons for download, install, and launch are black/orange/white respectively

Notes

There are some superfluous @ts-ignore comments in an appstore ui file - I think my IDE is bugged because the exact same file isn't showing those errors in the homepage ui. It compiles and runs as expected all the same.

Having all the SVGs in triplicate in the repo is really unfortunate.. is there a way to deduplicate these
