Description

Similar to https://github.com/ProxymanApp/proxyman-windows-linux/issues/507, we should implement the Client Certificate

How Client Certificate works?

Diagram: Client app -> Proxyman -> Real Server
When a Custom Client Certificate is provided by the user, Proxyman will use this Certificate when making an HTTPS connection from [Proxyman -> Real Server]. Make sure [Client app -> Proxyman] side is using the original logic.
Custom Client Certificate only affects on [Proxyman -> Real Server]

Criteria

Similar to #507 , we should have a service to manage the client certificate and a class to represent the cllient certificate and store it in the user data folder with subfolder: client-certificates
Support import via P12 or Pem/Der and passphare (similar to #507 )
Client Certificate is using on this side: [Proxyman -> Real Server] and works with
HTTPS
WSS
If the current connection's Host & Port is matched with Custom Client Certificate -> use it
Support 0 is a wildcard
