Export EmailPasswordForm (#11)

# Export more utils and EmailPasswordForm

## ♻️ Current situation & Problem
In the Spezi-Web-Health-Components it would be neat if we could make use
of `useOpenState`. In the Spezi-Web-Template-App the same applies for
the `EmailPasswordForm`.


## ⚙️ Release Notes 
- export `useOpenState`, `misc`, and `EmailPasswordForm` in the
`index.ts`.
