fix: added enablePeerTraffic call to xray (#2179)

* fix: add enablePeerTraffic call to xray

* chore: remove unnecessary steps during xray TUN setup phase

* chore: move tun init from tun2socks code to ipcserver

* chore: rework xray routing
* get rid of redundant delays
* check if remote calls are successful

* chore: xray routing fine-tuning

* fix: add service qt deps to deployment build
