Sidebar pages stop fighting each other

If you flipped between Bookings, Services, and Analytics, you used to see three different in-page nav styles — plain text buttons, underline tabs, then pills — for the same job. They're all underline tabs now. Page titles like "Analytics — Revenue and client progress at a glance" are gone: the breadcrumb already says where you are. The Activity, Overdue, and Packages report tabs no longer wrap their list in an empty card with extra padding above and below it. Dashboard KPI cards lost their inflated chrome (28px top padding for nothing) and sit tight. Settings → Payments stops centering itself in a narrow shell that didn't match any other settings surface.
