Apply Roslyn/dotnet-format fixes across NeonSprawl.Server and
NeonSprawl.Server.Tests: collection expressions, concrete helper
return types, record XML docs, logging guards, quest store refactors,
and removal of redundant usings via GlobalUsings.cs. Extend
csharp-style.md with the recurring patterns.
Split HTTP verification reads into Assert in C# API and integration tests.
Add # Arrange/# Act/# Assert to GdUnit suites and keep Act free of assertions
where casts and busy guards are under test.
Audit all test files and bring them in line with formatting/style expectations by adding explicit AAA markers across server test methods and fixing GDScript test lint/format issues.
