Add button to go back to tracking view from dashboard listing

Problem description

Our current onboarding flow shows the users the tracking implementation details when first setting up Product Analytics but doesn't give them a way to go back to see these details again.

Proposal

Add a button to the dashboards list which gives the user a way of getting back to the tracking implementation details. This button will have a dropdown showing quick details. The tracking implementation details page will need to be tweaked when visiting after implementation has been completed.

Design

Listing	Implementation details

Differences between the pages

Implementation details (setting up)	Implementation details (going back later)

Implementation plan

1. Add a split button to the dashboard listing.
2. Move the SDK Host and SDK App ID fields to a shared location, as well as the code accordions.
3. Create a new instrumentation view for the dashboards app to render.
4. Add to the split buttons dropdown similarly to the compliance dashboard.
5. Link the left-side of the button to the instrumentation view.
6. Update specs.
