Fix release build break in ted caused by malformed conditional and missing System.Text import

[Copilot]

Release run 2.2.1-develop.163 failed during the cross-platform build matrix due to a compile error in examples/ted/TedApp.cs. The file had a malformed if statement and a missing using required by Encoding.

• Compile break in settings dialog flow

  • Repaired corrupted conditional in ShowSettingsDialog:
    • Saveif (dialog.WasAccepted) → if (dialog.WasAccepted)
  • Preserved the intended behavior: apply dialog values and persist view settings only when accepted.

• Missing namespace import

  • Added using System.Text; at file scope to resolve Encoding usage in UpdateContentSizeStatus.

using System.Text;

// ...

if (dialog.WasAccepted)
{
    dialog.ApplyTo (Editor);
    SaveViewSettings ();
}

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• www.jetbrains.com
  • Triggering command: /usr/share/dotnet/dotnet /usr/share/dotnet/dotnet exec --runtimeconfig /home/REDACTED/.nuget/packages/jetbrains.resharper.globaltools/2026.1.1/tools/net8.0/any/cleanupcode.unix.runtimeconfig.json /home/REDACTED/.nuget/packages/jetbrains.resharper.globaltools/2026.1.1/tools/net8.0/any/cleanupcode.exe Terminal.Gui.Editor.slnx --profile=TG.Editor Full Cleanup (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

This needs to be merged quickly.
