data(brand): verify final Wikidata batch

[Seungpyo1007]

Summary

• Cross-reference the last 77 Brand records (sorted indices 130-206) against Wikidata. Earlier batches already covered the first 130.
• Add a Wikidata entity URL to 54 confirmed records only. Confirmation requires an exact normalized English name or alias (or the search hit's exact matched text), a non-deprecated inception year equal to founded_year, and a matching official website domain or country.
• Leave 23 records unchanged where the name, year, and website or country do not all agree.

Verification

• The same gate reproduces all 49 Wikidata URLs from the second batch, and it does not rewrite those records.
• Each of the 54 diffs adds exactly one https://www.wikidata.org/wiki/Q... URL to source_urls.
• git diff --check passed.
