Incremental onboarding fixes and guided intake enhancements

♻️ Current situation & Problem

This PR introduces incremental fixes and feature additions to the onboarding flow identified during development and testing.

Specifically:

• Scrollable elements in the consent form were difficult to dismiss and required scrolling back to the top.
• The on-screen keyboard obscured certain text inputs (e.g. name fields) in the consent form.
• TypeScript build errors were causing test failures, particularly related to ChoiceQuestion.
• The onboarding flow required a guided intake step to better support eligibility checks and downstream data collection.

These issues impacted onboarding usability and caused CI instability.
