feat(onboarding) - add engagement form for Germany

[gabrielseco]

I added a new step that we load when the the feature flag for steps is used, added tests to cover save the form, retrieve data, render schema

---

Note

Medium Risk
Adds a new dynamic onboarding step with new schema/data fetches and a dedicated update mutation, which can affect step inclusion/navigation and form submission behavior for Germany flows.

Overview
Adds a new engagement_agreement_details step to the onboarding flow (wired through OnboardingFlow components and the main useOnboarding hook) that can be dynamically included based on whether the country-specific schema returns fields.

Introduces new API hooks to fetch the engagement agreement schema and any previously-saved details, plus a new mutation to persist the step via the /engagement-agreement-details endpoint; submission/validation/loading/meta/initial-values logic is updated to incorporate this step.

Updates the example app to render the new step, show a Germany-specific title/description with a Zendesk “Learn more” link, and include the step in the review UI; adds Germany to country fixtures and adds integration tests covering schema load, value prefill, and saving/navigation for Germany with dynamic_steps.
