feat: accept classname on loginview (and login) for consumer styling (#954)

[frano-m]

Summary

• Extends Login Props and LoginViewProps with BaseComponentProps, adding an optional className.
• Forwards className from LoginView → Login → root LoginWrapper, so consumers can style/position the login card without an extra wrapper element.

Closes #954

Test plan

• Existing tests still pass (npm test)
• npx tsc passes
• Consumer usage works:

  const StyledLoginView = styled(LoginView)\`
    align-self: center;
  \`;
  <StyledLoginView providers={providers} />

  renders the login card with the styled-component class applied to its root.
• Existing consumers that don't pass className see no change.
