feat: wrap all authenticated pages in DashboardShell, fix site card actions

- Move DashboardShell wrapping to layout-content.tsx for all dashboard
  pages (home, integrations, pricing) instead of per-page
- GlassTopBar derives page title from pathname (Integrations, Pricing)
- Site card: gear icon now opens site settings, separate trash icon for delete

app/page.tsx
