fix: list as members only the accounts the node has admitted

The Members list showed the hub's membership, which an account gains when it
accepts the invitation or redeems a link, before it has presented its code to
the node. The node's roster is the authority (MESHBAY_DESIGN.md §3.4), so
the list now crosses the hub's members with the sealed group roster the node
already sends every connected member. An account the node has not admitted
yet is shown to the owner alone, as waiting for its code, with the Remove
button; other members do not see it. When the roster cannot be read, the
hub's list is shown as before.

groupRoster() takes { fresh: true } so the page sees who joined since the
connection opened.
