Incorrect object data on specific record on second page of results

Logging this as an AdminUI issue as it is not reproducible with `crash`

### CrateDB version

5.4.0

### Steps to Reproduce

```sql
CREATE TABLE adminuiissue (o OBJECT,descr TEXT);
INSERT INTO adminuiissue(o,descr) SELECT {},'This is another one' FROM generate_series(1,17);
INSERT INTO adminuiissue(o,descr) SELECT {},'Something else' FROM generate_series(1,81);
INSERT INTO adminuiissue(o,descr) SELECT '{"tschritter":{},"code":"abcde1","tz":"Europe","shifts":[],"assignees":{},"language":"de","id":123,"plant_key":"abcde1","stations":{}}','Look at this record';
-- From the AdminUI
SELECT * FROM adminuiissue ORDER BY descr ASC;
-- Expand the o object for "Look at this record", note there is data in there
SELECT * FROM adminuiissue ORDER BY descr DESC;
-- Go to the bottom of the second page of results
-- expand the o object for "Look at this record"
-- note there is NO data in there
```

Reproduce the SQL example in the AdminUI, checking the expanded object for “Look at this record” on both result pages and with both sort orders. Trace the pagination and object-expansion entry points to find why the second-page record loses its data. Done when the object displays consistently on both pages and the reported reproduction no longer occurs.
