fix: correct LoginContext setter types and remove dead PASSWORD_RESET_ERROR code

LoginContext setFormFields/setErrors are useState setters that accept
updater functions, so their types should be Dispatch<SetStateAction<...>>
rather than plain function signatures.

PASSWORD_RESET_ERROR was checked in ResetPasswordPage but no code path
ever set status to that value, making the conditions dead code.
