Past videos shouldn't be on the profile landing page

[jace]

The past videos section on the profile page conflicts with the current future-focused layout of the page. It should be moved into a separate tab pending a better design for the page.

The filter for the videos – featured sessions – is not a clean workflow for account admins, so in 2023 the top-featured videos could be from 2019, which the user may perceive as an irrelevant distraction from whatever they're seeking on the page.

It may be prudent to remove this section entirely pending a spec for how account admins have control over the page (instead of project editors, who currently source the data).
