Miheichev Aleksandr Sergeevich	49d197e37f	i18n(ru): translate new strings and fix terminology casing (#9207 ) Translate 11 new strings introduced in upstream and fix casing of several technical terms in ResUI.ru.resx. New translations (9 existing + 2 added): - TbAllowInsecureCertFetch, TbAllowInsecureCertFetchTips — insecure certificate fetch checkbox and MITM warning tooltip - TbHost — host field label - TbSettingsDefUserAgentTips — updated transport list (raw/http, ws, gRPC, xhttp) - TbSettingsSendThrough, TbSettingsSendThroughTip, FillCorrectSendThroughIPv4 — local outbound IPv4 setting - TbSettingsUdpTestUrl, menuUdpTestServer — UDP test URL and menu item - TransportExtra, TransportExtraTip — XHTTP Extra raw JSON Terminology fixes: - "V2ray" → "v2ray" (core name is lowercase by convention) - "[Anytls]" → "[AnyTLS]" (canonical protocol spelling) - "LAN порт" → "LAN-порт" (hyphen per Russian grammar) All translations use canonical casing for protocols (VMess, VLESS, Shadowsocks, Trojan, WireGuard, Hysteria, TUIC, AnyTLS), cores (Xray, sing-box, mihomo, v2ray) and abbreviations (TLS, DNS, UUID, HTTP, IPv4, MTU, TUN, PAC, SOCKS, gRPC, XHTTP).	2026-04-29 14:43:35 +08:00
