Working on several @pixelfed webUI improvements!

✨ Inline modals (view posts/profiles without losing your feed position)
✨ New ComposeUI
✨ Web Push Notifications
✨ Multiple account switcher (easily toggle between logged-in accounts)
✨ Better low-bandwidth/offline support

Maybe it's a good thing that Apple expired my builds, it's been a while since I've worked on the webUI and it needs a lot more attention!
