WebSocket proxy for JSON-RPC 2.0 server

Changes for 0.16 - 2023-12-15T07:48:13+00:00

• Mojo::WebSocketProxy::Dispatcher changes:
• Use Log::Any instead of Mojo::Log in Dispatcher;
• Avoid string interpolation to solve warning due to the uninitialised value of $c->tx->remote_address;
• Add fallback value for cases when remote_address can't be resolved;
