Rewrite forms to react-hook-form

[fujiwaracj]

There is an ongoing discussion on a pr on how server actions and react-hook-form will be implemented in the next version of the library, as of now this hasn't been merged and is still in a draft state.

For now, startTransition and instantiation of a FormData class can be used so that the required formData can be passed through a server action. Not that great since it doesn't validate if the form submission was successful or not but at least it's working and development can still be resumed.
