fix(sub): stop appending the node name to subscription remarks (#5231)

The #5035 change tagged node-hosted entries with the node name to
disambiguate multi-node subscriptions, but the node name is
panel-internal and leaked into the profile names end users see in
their client apps. Drop the suffix entirely — remarks are the
admin-set inbound remark again.
