fix: react-doctor → 64/100 (Bugs 122, Perf 286, A11y 613, Maint 436)

- CartContext: lazy initializers replace mount-only useEffect hydration; remove 8 no-initialize-state warnings - Toast/AdminSearchInput: React 19 useContext/use + drop forwardRef (3 no-react19-deprecated-apis) - ProductFormModal: lazy initializers + useSyncExternalStore for mount; parent adds key=editingProduct.id - InstallPrompt: useReducer for prompt state (no-cascading-set-state) - QRScanModal: ref-based latest-callback pattern replaces useEffectEvent deps mistake - OnboardingFlow: functional setState (rerender-functional-setstate) - UsersPage/StopsCalendar/FeaturesAndStats: lazy initializers (rerender-lazy-state-init) - FAQClientPage: server-side brand settings fetch via getBrandSettingsPublic in layout; remove supabase import - LandingPageWrapper: href='#' → href='#top' (anchor-is-valid) - TuxedoVideoHero: replace animate-bounce with ease-out-expo (no-inline-bounce-easing) - ProductTableClient: useCallback for handleDeleted (jsx-no-new-function-as-prop) - excel-parser: pre-compile delimiter regexes (js-hoist-regexp) - water-log/settings: Promise.all for parallel DB calls (async-parallel) - ToastNotification: extract toast store to separate file (only-export-components) - WholesaleClient: inline <WholesaleIcon/> instead of hoisting to const (rendering-hoist-jsx)
