improvements in handlers in IdentityComponentsEndpointRouteBuilderExt…

[Brano5]

This pull request simplifies how client information is handled during login and logout events in the identity endpoints. Instead of passing a complex ClientIdentification object, only the client's IP address is now passed to the handler delegates. The related code for collecting additional client details has been removed, streamlining the logic.

Delegate and handler signature changes:

• Changed the LoginHandler and LogoutHandler delegate signatures to accept only the ipAddress string instead of a ClientIdentification object. (IdentityComponentsEndpointRouteBuilderExtensions.cs)

Simplification of client info usage:

• Updated all usages of loginHandler and logoutHandler within MapAdditionalIdentityEndpoints to pass only the IP address, removing the creation and use of the ClientIdentification object. (IdentityComponentsEndpointRouteBuilderExtensions.cs) [1] [2] [3] [4] [5]

Code cleanup:

• Removed the ClientIdentification class and the GetClientIdentification method, as they are no longer needed. (IdentityComponentsEndpointRouteBuilderExtensions.cs) [1] [2]
