Hosted proof keys require an exact application origin

Hi,

I just tried very quickly to connect via the application and I have the following error message:

Hosted proof keys require an exact application origin.

I can reproduce what appears to be the same origin/capability problem in the TaskNotes iOS app with an existing hosted mdbase collection.

Steps to reproduce:

1. Open TaskNotes on iOS and choose Connect/Reconnect.
2. The mdbase authorization page identifies the application as app.tasknotes.dev.
3. Select the existing hosted collection, review access, then tap Set up and allow access.
4. mdbase confirms Access approved and says it is returning to the application.
5. Back in TaskNotes, the app displays: The application origin does not match this capability.
6. Reconnecting repeats the same flow and error.

Expected: TaskNotes iOS should accept the returned capability and open the selected collection.

Additional observation: the authorization page reports compatibility/setup requirement tasknotes.task v0.3.0-rc.3; the collection is successfully hosted and the permission grant itself completes without error.
