fix(lint): corregir últimos 3 errores react-hooks/set-state-in-effect en CI

- useElectron.ts: lazy initializer para isElectron e isTauri, elimina useLayoutEffect
- useSearchHistory.ts: lazy initializer leyendo localStorage en useState directamente
- CustomUserWidget.tsx: añadir eslint-disable-next-line para setState sincrónico
  necesario en el guard temprano (no-customTypeId) dentro de useEffect async
