Date Formatting Fix and New Onboarding Feature

A new feature flag has been added for our upcoming onboarding flow. This allows us to gradually roll out improvements and test them thoroughly behind the scenes, ensuring a smooth and delightful experience when it's fully launched.

Finally, we've made some helpful improvements to the accessibility of our navigation component. This change makes it easier for all users to navigate through the application, contributing to a more inclusive and user-friendly experience for everyone.
