Regroup and reword the research project cards

Order the initiatives by family rather than by date, title them the way
the repository does, and give every description one shape.

Swap the homepage feature to the measurable mistakes article, and trade
descriptions with the WhatKey card so each says what it is actually
about. Add store links to the article index CTA.
