fix: handle null pagination parameters in latest event search query

Ensure proper defaults are used when pagination parameters are not
provided, this helps to have a query working for all DBs especially
SQL Server to avoid

```
The ORDER BY clause is invalid in views, inline functions, derived
tables, subqueries, and common table expressions, unless TOP, OFFSET or
FOR XML is also specified.
```
