Currently getAllForms() is called only once, at login. If the backend updates a form (for example, Contact Tracing) while the user is already logged in, the app keeps using the outdated schema. The app should check form versions through a new lightweight API and refetch the schemas only when a version mismatch is found.

Scope:

• Call the new Form Versions API at agreed trigger points, such as app launch, app resume from background, before opening a form, or after a sync. The exact points are to be finalized.
• Compare the returned versions with the locally stored form versions.
• If any version differs, call getAllForms() and store the updated schemas locally.
• If versions match, skip the full fetch.
• Handle offline cases and API failure gracefully by continuing with the locally stored forms.

Acceptance criteria:

1. A logged-in user receives the updated form schema after the backend changes a form, without logging out and back in.
2. getAllForms() is called only when a version mismatch exists.
3. Local form versions are updated after a successful fetch.
4. There are no crashes or blocked flows when offline or when the API fails.
