[Onboarding] - Dashboard transition

[getheobald]

Description

As a new member, I want my dashboard to transition to the standard view so I’m not stuck in the new member experience after I’m fully onboarded

Acceptance Criteria

• New member dashboard has a defined expiry condition (time-based, team-join-based, or both?)
• Extension: new members can opt out of the new member dashboard early
• Dashboard transition is handled separately from team join
• No broken state between dashboards

Proposed Solution

There's already existing route logic that decides which home page to render. I can just add a newMember case there. If user is in the new member state, render NewMemberHomePage instead of MemberHomePage. Just need to figure out how to assign a user's state after we decide on the expiry condition.
