Only enable SignalR detailed errors in development

Changed EnableDetailedErrors to be conditional based on:
- Debugger attached (DebuggerHelper.IsAttached)
- context.HostingEnvironment.IsDevelopment()

Updated ConfigureServices to accept WebHostBuilderContext to properly
access the hosting environment instead of directly reading environment
variables. This prevents detailed error messages from being exposed in
production builds, which is important for security.
