fix(footer): follow the brand for the frontend source link

The version link was a module constant naming github.com/luxfi/explore, so
every brand's footer sent readers to Lux's repo — explore.hanzo.ai showed
"Frontend: v1.1.30" pointing at the Lux org. Brand identity in this image is
resolved per host, and the source link now resolves with it: ChainBranding
gains sourceUrl (NEXT_PUBLIC_BRAND_SOURCE_URL for external operators, like
every other branding field), so Lux keeps its own repo and Hanzo, Zoo, Pars,
SPC and Osage each name theirs.

Also sets Hanzo's copyright to Hanzo AI, Inc., the entity its terms, privacy,
DPA and brand.json all name; Hanzo Industries Inc. predates that consolidation.

chainRegistry.spec.ts asserts a brand host surfaces no other org's name or URL
in what the footer renders.
