feat(home/oyez): replace text title with the linked Oyez! banner

Swap the 'oyez.ariege.io' script-text title for the brand Oyez! wordmark
banner (self-hosted SVG), wrapped in an external link to oyez.ariege.io
(new tab, subtle hover fade). Sized responsively: w-5/6 of the column on
mobile, filling the column capped at max-w-md (448px) on desktop.
