Subject: [PATCH] fix(worker): raise SignalR
 MaximumParallelInvocationsPerClient

Default of 1 serializes every hub call on a connection - a slow one
(GetTicketProjects hitting an unreachable ticket system, 10s timeout)
blocked unrelated calls like UpdateList/UpdateListConfig behind it for
the same duration, making list-settings save appear to hang.
