hscontrol/state: fix online status reset during re-registration

Browse Source 
Two fixes to how online status is handled during registration:

1. Re-registration (applyAuthNodeUpdate, HandleNodeFromPreAuthKey) no
   longer resets IsOnline to false. Online status is managed exclusively
   by Connect()/Disconnect() in the poll session lifecycle. The reset
   caused a false offline blip: the auth handler's change notification
   triggered a map regeneration showing the node as offline to peers,
   even though Connect() would set it back to true moments later.

2. New node creation (createAndSaveNewNode) now explicitly sets
   IsOnline=false instead of leaving it nil. This ensures peers always
   receive a known online status rather than an ambiguous nil/unknown.
