patternihaandClaude Opus 5.5 747b153333 TUN inbound: Error out when autoSystemWfpBlockLeak or autoSystemDnsToGateway cannot apply
As asked in review, rather than run without them:

- The config is rejected, also by xray -test, for autoSystemWfpBlockLeak
  without autoSystemRoutingTable, or with "dns" but without dns, on
  Windows, and for autoSystemDnsToGateway without gateway on Linux.
- Xray does not start when the filters cannot be added, now on every
  Windows version, or when the system DNS cannot be set on Linux,
  instead of logging it and running without them.
