fix: professional profile not loading or saving correctly

- Fix typo aditional_address -> additional_address in toDocument() and fromDocument()
- Clear ProfessionalFormProvider before fetch in initState() so TextFormField initialValue always applies to fresh data
- Add clear() to ProfessionalFormProvider; call it on logout to avoid leaking data between users
