feat(site): complete playground and branding

[Seungpyo1007]

What & why

Completes the homepage's published-resource surface:

• adds laptops, monitors, and software to the Playground selector and endpoint list; and
• replaces the TechAPI header and footer placeholder mark with the supplied brand image.

Games remain intentionally absent because the Pages deployment excludes the game dump.

Source

Brand image supplied for this repository. Resource availability verified against the deployed static v1 index and list endpoints.

Checklist

• Verified laptops, monitors, and software list endpoints and detail slugs
• Kept games excluded from the public Pages API
• No dataset records or TechEngine files changed

Closes #19

Warning

Tracked verified coverage is below 50% for watch 2.5% (11/433), brand 4.8% (10/207), tablet 5.0% (174/3455), soc 5.8% (123/2104), smartphone 9.1% (8453/93396), all 9.5% (10028/105742), gpu 12.0% (244/2030), pda 19.3% (27/140), 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.
