- dashboard.html: admin "App installs" card — table of user · platform · version · OS ·
first/last seen, from GET /api/v1/admin/installs (loadInstalls).
- index.html: replaced the long inline link with a compact white "Download app" button in
the blue top header (top-right); hidden when already inside the desktop app.
