fix(studio): use table + card component in log retention upgrade prompt (#48713)

## 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

Non-blocking review nit from #48452 (comment:
https://github.com/supabase/supabase/pull/48452#issuecomment-5128918096)

## Test plan
- [x] `pnpm --filter studio typecheck` passes
- [x] `pnpm --filter studio run lint:ratchet` passes (no new warnings)
- [x] Prettier check passes
