feat: merge app store and connections page

[rolznz]

Closes #1548

TODOs:

• review component inconsistencies with design (tabs, badges) ok for now
• do we need to merge app detail with the app store page (I think it adds complexity) - added but editing is still done on the show app page
• implement improved app detail page
• Re-add the links card (even though you're already connected to the app you might want to visit the site)
• How to remove the duplication between the app store: and the connection detail:
  • On the app store, if you click on an app that is already installed, go to the app detail of the first connection for that app.
  • If there are multiple connections show a dropdown on the detail page (with the currently selected connection)
• On app detail page, hide almost everything from the connection details in advanced (id, pubkeys etc)
• Payment tools and merchant tools should be moved below social media
• For isolated apps, add a "Balance" card next to total spent, total received, which can have the buttons for top up and draw down
• For subwallets, add a lightning address card
• Change top up / draw down to increase/decrease
• Merge with tw fixes
  • Does dropdown selection work for entire item?
• Remove unused code in app detail header

The app details page looks a bit odd with the connection card on top and the space to the right, doesn't it?

@reneaaron yeah, this would be solved if I implement Jakub's real design which merges the app detail properly into the app store app page. I will try to do that (I was hesitant because it duplicates code, but maybe there's a way)

Overall it feels really nice, great job! 💯 Just some minor feedback:

1. The BuzzPay app looks a bit odd currently:

2. I still think the "disconnect" button is way too prominent and could be moved into the dropdown

3. Could we make the permission details (and collapse them by default)? What do you think?

@reneaaron good catch - buzzpay now looks like this:

Not that great but maybe ok for a first iteration.
