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

[Seungpyo1007]

The homepage still featured last-gen flagships (S25 Ultra, Pixel 9 Pro, iPhone 16…). Updated to the current generation that's in the dataset:

• Featured cards: Galaxy S26 Ultra · iPhone 17 Pro Max · Pixel 10 Pro · OnePlus 14 · Xiaomi 15 Ultra (no 16 yet) · Galaxy Z Fold7
• Hero terminal demo: Galaxy S26 Ultra · Snapdragon 8 Elite Gen 5 · RTX 5090
• Endpoint examples + playground placeholder updated to match

All slugs verified to resolve against the live dump. Refs #1

Closes #19

Warning

Tracked verified coverage is below 50% for watch 2.9% (11/378), brand 5.3% (10/189), tablet 5.7% (174/3048), soc 5.8% (123/2104), smartphone 9.4% (8453/90118), all 9.8% (10028/101954), gpu 12.0% (244/2030), pda 24.5% (27/110), and 1 more.
Tracked coverage excludes records missing the verified field; see the Missing verified column for those records.
This does not fail validation. Keep imported records verified: false until manual audit, but treat this as follow-up verification work before relying on the affected categories as curated data.

Validation notes

• Full advisory outlier listings are suppressed on successful runs because they are dataset-wide and mostly stable between PRs.
• Failure runs still include a detailed log excerpt for debugging.
