Update onboarding to demonstrate day view #1175

Priority

High

Feature Description

We added the ability for the user to track daily tasks and see their daily agenda side by side. We need to ensure that new users are aware of this capability and how to access it.

Include info about:

• The high-level idea of iterative scheduling
• The difference between the Now/Day/Week pages

Requirements

• After the user completes onboarding, navigate to /day (we're currently sending them to /, which is the week route.
• Tasks for the current day are created during the onboarding — we could force the user to do it themselves or do it for them in the background.

Implementation Guidance

• Consider converting shortcut overlay to a sidebar and then including a tab for the Day Planner onboarding walkthrough
  • After the onboarding is complete on the day view, then show the shortcut overlay in the sidebar content.
• Include checkboxes that show whether the user has added/deleted/edited a daily task

Use Case

This'll help users understand what makes Compass different and how to get started earlier.
