## Summary
- Refactor the SQL Editor / Logs "Log retention" upgrade-prompt dialog
to use the design system's `Card` + `Table` components instead of a
custom flexbox-div table, matching the pattern in
`apps/design-system/registry/default/example/table-demo.tsx`
- No behavior or data change
Fixes FE-4034
