style(wizard): reflow FirstRunWizard and WizardStateSmokeStep to csharpier

Preflight Block E (`dotnet csharpier check`) flagged two reflows
in the v1.5.2 code: the ForgeBronzeDim Vector4 constant needed
multi-line form, and a handful of switch arms / long Plugin.Config
chains in WizardStateSmokeStep needed line-breaks at csharpier's
print-width. Pure formatting — zero functional change. Block D
build stays clean, Block E now passes.
