Claim/takeover app UI

[franzaps]

Need somehow to guide dev through commands to be run in CLI, paste result and sign with browser extension, generate a 30509 event

[franzaps]

This could also go in the developer section where they edit their apps, etc

[franzaps]

It should support apps and also PWAs

[franzaps]

Should show state of app (indexed, claimed, taken over, 30509 expired, etc)
