A group owner's settings: who was invited, and which other nodes asked to host.
Renders the shipped `GroupSettingsPanel` with `fetch` stubbed: one member, one
unanswered invitation, one node asking to host and one already approved. Then
clicks Approve on the request and reports what reached the hub.
