Fix Telegram NyxID reply rendering

[louis4li]

Summary

• Fix Telegram NyxID binding and init prompt rendering so interactive links degrade cleanly.
• Keep Telegram relay replies on text streaming when CardKit streaming is globally enabled; CardKit streaming now only applies to Lark turns.
• Add regression coverage for Telegram text streaming versus Lark CardKit streaming routing.

Test plan

• dotnet test test/Aevatar.GAgents.ChannelRuntime.Tests/Aevatar.GAgents.ChannelRuntime.Tests.csproj --nologo --no-restore --verbosity quiet
• bash tools/ci/test_stability_guards.sh
