refactor: use the useWatch from react-hook-form to get around the r…

…eact-compiler memoization issues (#376) the react-compiler doesn't play well with the `form.watch` api as it breaks the rules-of-react in an unobvious way, thus loosing the reactivity that was intended. to get around this you need to wrap it in `useMemo` to trick the compilter. this change consumes the `form.control` in the provided `useWatch` hook by `react-hook-form` to maintain the reactivity of the original api without breaking the rules-of-react, thus letting the react-compilter work flawlessly without any hacks.
