fix: check whether the dst port is within the specified range

[laburaps]

After iterating the sniffers list in TCPSniff, if there is a sniffer that meets the protocol and port requirements, then inWhitelist is set to true, and the subsequent sniffDomain process is entered. However, in sniffDomain, there is no re-check on the port, which leads to a situation where, even though both HTTP and TLS sniffers are configured to sniff different ports (for example, HTTP sniffer only sniffs port 80, and TLS sniffer only sniffs port 443), in practice, HTTP sniffer will sniff all requests on port 443 (and TLS sniffer will sniff all requests on port 80).

Solution: Simply add another check for the supported ports in sniffDomain.
