Now that @bytelyst/ui@0.1.6 ships <CardButton>, replace the local
`.card-button` className shim (added to layout-fixes.css §25 in the
prior commit) with the real primitive.
Conversions:
- components/StrategyWizard.tsx — risk style (3 cards) + hours pickers
- views/SimpleView.tsx — new-buy + manage-holding plan cards
- tabs/MyStrategiesTab.tsx — diagnostic accordion toggle
Removes layout-fixes.css §25 (.card-button) — no longer needed.
Updates docs/ui/UI_AUDIT.md Pattern A to reflect that the design-system
fix has shipped.
