fix(data): add source citations for 45 laptop/monitor records

Upgrade uncited laptop/monitor records from dataset-only provenance to
source-verified by adding authoritative manufacturer/Wikipedia citations
that confirm the stored specs, and set verified:true. Original dataset
provenance URLs are retained alongside the new sources.

- 24 laptops: Apple MacBook 12/Air/Pro (2017), Microsoft Surface Laptop
  (1st gen), Google Pixelbook, ASUS Zenbook 14 OLED UX3405MA/UX3405CA;
  cited against Apple support pages, Wikipedia, Google and ASUS spec pages.
- 21 monitors: Dell UltraSharp/S-series, Gigabyte AORUS/M/GS series,
  MSI G/MAG series, Samsung Odyssey, LG UltraGear, BenQ, ViewSonic;
  cited against manufacturer spec pages.

Value corrections to match the cited source (never invented):
- Google Pixelbook weight 1100 -> 1110 g (Google: 1.11 kg)
- MacBook Air 2017 weight 1340 -> 1350 g (Apple: 1.35 kg)
- Surface Laptop weight 1252 -> 1250 g (Wikipedia/Microsoft: 1.25 kg)
- LG 24GN60R size 24.0 -> 23.8 in (LG spec)
- Samsung Odyssey G9 49" DQHD resolution 3440x1440 -> 5120x1440, ppi 76 -> 109
