Joseph Doherty 795eee72e3 client/dotnet: backfill XML doc comments to satisfy analyzers
Adds missing <summary>/<param> docs across the .NET client library and its
test suite so CommentChecker reports zero issues. TreatWarningsAsErrors
requires the analyzer surface clean before publishing the NuGet package.
