[ios] add SSHClient gomobile binding for in-app terminal

Exposes SSHClient + SSHTerminalListener to the iOS app, mirroring the
Android binding. Connect() auto-detects the server type via banner
inspection and selects the auth path: NetBird-SSH with JWT triggers the
device-code OAuth flow via the existing URLOpener; NetBird-SSH without
JWT uses the NetBird private key; regular SSH falls back to the NetBird
key then optional password. The client dials through the running tunnel
with a plain net.Dialer and streams PTY output back to Swift via the
gomobile-bound listener for rendering in the terminal view.

Adds a config field and sshState() accessor to the iOS Client so the
SSH client can reach the active config and engine.
