[Onboarding] - Onboarding checklists summary

[getheobald]

Description

As a new member, I want to see a summary of key info I learned or things I did during the onboarding checklist phase so I can reference what I learned.
Below the widgets on the dashboard, we'll display info about tasks the new member already completed in case they wanted to read something again.

Acceptance Criteria

• Read-only list of checklist info is displayed on dashboard
• Content is imported from checklist data rather than having to be re-entered manually
• Does not mess with existing onboarding checklist functionality

Proposed Solution

No backend work needed because I can call the existing get users checklists endpoint and useUsersChecklists hook. Just need a new component that displays a read-only list of the checklist items.
