[rate-card] Enhancements

For showcase gallery, add categories like via horizontal scroll to view top 5 IG content, top performing YT videos, maybe Spotify don't need since the stats just okok

Kinda like this but imagine the top is like IG embeds, bottom are YT videos, then website visitors can scroll horizontally and click to see more - that way size of embed is the same for each row, looks better
