e2e: add UDP forward QUIC sniffing test

Browse Source 
Add TestUDPForwardQUICSniffing: sends a real captured QUIC v1 Initial packet
through the UDP forward handler (with sniffing enabled) and verifies the
datagram is echoed back. Covers the QUIC ClientHello/ServerHello sniff path
in x/handler/redirect/udp and x/handler/forward/local.
