Fixes: https://github.com/ente-io/ente/issues/1440
There were two issues:
- It was a backward incompatible change to change the scheme from ente:// to
next://. Revert.
- We also need to setup a top level redirect when the user presses back without
making any changes to their subscription.
**Tested by**
Running payments app and desktop app locally, and verifying that after
interactions with the payments endpoint we go back to the desktop app's actual
contents correctly.
- Use the shared yarn monorepo configuration
- styled-components => emotion (since that's what the rest of the code uses)
- Remove Sentry (since it's gone elsewhere)
Manav: To avoid accidentally spilling out any secrets, squash and
import. However, the overwhelming majority of the work in the original code was
done by Abhinav <abhinavk.grd@gmail.com> so set them as the author for the
commit.
