fix(chat): KeyNotFoundException dans HubConnectionManager.OnConnected
ChatUserNames n'etait jamais alimente (relique d'un SetUserName disparu),
ce qui faisait lever KeyNotFoundException a chaque connexion SignalR et
fermait immediatement la connexion cote client ("Déconnecté (The server
closed the connection...)" dans PostIt).
- IConnexionManager.OnConnected prend desormais le userName en parametre
- HubConnectionManager.OnConnected alimente ChatUserNames et ChatCxIds
- ChatHub.OnConnectedAsync passe le userName resolu depuis les claims
Inclut aussi les changements PostIt lies (bandeau de statut avec
commande d'action, handlers Reconnecting/Reconnected/Closed).
