fix: Incorrect password field on account creation

[SandPoot]

Don't be too cruel with me, i was just attempting to check out stoat and noticed that trying to create an account asks you to "Enter your current password" and doesn't have password suggesting.

I have replaced "password" with "new-password" according to the file Form.tsx, this is not AI-assisted, i've done it raw on my web browser.

thank for the work

this will break the api call with 422: Unprocessable Entity since the request sends password not new-password

to complete this pr we would need something like
L66-71

  // Map field types to form field names
  // "new-password" should submit as "password" for API compatibility
  const getFieldName = (field: Field) => {
    if (field === "new-password") return "password";
    return field;
  };

L85

              name={getFieldName(field)}

in packages/client/components/auth/src/flows/Form.tsx

I'm sorry, i'll have to check this later, ideally, i wouldn't want stuff to be hacky like this, but if that's fine i'll just apply it
