When all forms migrated, we should make sure all ha-form related components (including selectors and this action component) are in the ha-form folder so it's easier to indicate that one should use ha-form.

Don't create static objects in render, as they will be recreated on every render (every state change), they will not pass a strict equality check and thus will cause a re-render down the line while not needed.
