PageShell gains an optional titleHref prop — when set, the header title
renders as an <a target="_blank"> with hover underline. Also wires this
into the homepage app gallery (shared-ui/AppsPage): the grid card title
is now an anchor to /{app.id}, while the rest of the card still opens
the existing detail modal. Card converted from <button> to role=button
so the nested anchor is valid HTML.
