fix: corregir errores de renderizado React y React Router

- Corregir MenuSheet: instanciar componentes Icon correctamente (<Icon /> en lugar de {icon})
- Mover ErrorBoundary fuera de BrowserRouter para evitar errores de contexto
- Eliminar Link de ErrorBoundary (usar window.location.href en su lugar)
- Cambiar process.env.NODE_ENV a import.meta.env.DEV en ErrorBoundary
- Los errores 'Objects are not valid as a React child' y 'basename is null' ahora resueltos
