fix(core/presentation): Fix null reference in FieldLayout components

[christopherthielen]

The fix was adding a default value when destructuring the validation prop

const { label, help, input, actions, validation = {} } = props;
const { hidden, messageNode, category } = validation;

Also converted to functional components

that simple huh? cool!

is the rest just prettier being aggressive?

Nice! I am a huge fan of using functional components where possible. They help to reduce bundle size and custom hooks will help unlock abstraction, which I see being a big advantage for migrating controller logic that is now replicated across providers.
