adding notification on the agent client side

[yeabtsegataye]

1. back end we add on column on the message table that is "seen" it is Boolean and when the chat is clicked it will be setted to true and when the client send it .. it will be setted false by default so we will show the notification by counting the false one for that specific chat and
   setting
   it
2. front end get the data and display it side by side to the chat if we clicked the chat it must be converted to 0 or default form
