Relay Update: TCP Support for Non-Standard Ports

[kelvinzer0]

Description:

• All TCP ports other than 80 and 443 are now handled by the relay.
• The previous UDP relay has been updated to support TCP relay as well.
• These changes improve relay flexibility and protocol handling consistency.

Impact:

• Users can now use the relay for TCP on custom ports other than the standard ports.
• There have been changes to the behavior of the previous UDP relay server and the current ${protocol tcp/udp}:${target_host}:${target_port}|{data}
