* blog(dsv4-day0-day43): add FAQPage JSON-LD to match other posts

Every other post in content/blog/ ends with a <JsonLd> FAQPage block;
this republished article was the only one missing one. Six Q&As anchored
to verified data points in the article (MI355X 100x in 26 days,
$0.156/M tokens on GB300+MTP, HCA m'=128 / CSA m=4 → 50x KV reduction at
1M, B200 300k→500k tok/s/MW at 50 tok/s/user, MegaMoE 1.92x theoretical,
Day 0 stack support matrix).
