chore(site): refresh featured devices to the latest generation

The hero terminal and featured cards still showed last-gen flagships. Update to the
current generation present in the dataset: Galaxy S26 Ultra, iPhone 17 Pro Max,
Pixel 10 Pro, OnePlus 14, Galaxy Z Fold7 (Xiaomi 15 Ultra kept — no 16 yet), and the
hero demo to Galaxy S26 Ultra / Snapdragon 8 Elite Gen 5 / RTX 5090. Also updates the
endpoint examples and the playground placeholder. All slugs verified to resolve.
