add expand/collapse option to landing page to quickly scan annotations in models

[vanaukenk]

From workbenches calls:

We'd like to add a new feature to the Noctua landing page to allow users to expand or collapse models so they can easily scan the individual annotations in models.

Thx.

@tmushayahama I added this to the Noctua 3.0 project, but I can't seem to add it to the Noctua landing page project. I'm not sure why,
