fix(i18n): localize Chinese Xray labels (#6202)

* fix(i18n): localize Traditional Chinese Xray labels

Several navigation, outbound, balancer, VPN, and DNS labels still displayed their English source text in the zh-TW interface. Translate the non-protocol labels while retaining established Xray terminology.

* fix(i18n): localize Simplified Chinese Xray labels

Mirror the reviewed Xray UI coverage in zh-CN so the same labels no longer fall back to English there.
