redesign: admin pages — clean 2026 style, no heavy boxes

- AdminHeader: stripped backdrop-blur, cleaner typography, shorter
- Tabs: softer pill bar, no outer border, rounded-lg background
- Section wrappers: removed shadow-sm, bg-card/82, border→border/50
- ScripFlowNode: softened borders, removed card bg, cleaner label
- All 8 section wrappers updated with replace_all
