fix(pricing): state the same domain count per plan on the homepage

The homepage cards gave no domain count to Side Hustle or On the Rise and
gave three to Powerhouse, while the in-app plan page (odoo/upsell.html) and
the published terms.html both say one domain for Side Hustle and three for
On the Rise and Powerhouse. Cards now read 1 / 3 / 3; PRODUCT.md and
llms.txt carry the same counts so no future page has to guess.
