Combine pairs of DateTime predicates on the same search parameter

[feordin]

Description

When we have a FHIR query like the following:
?issued=ge2024-04-22T00:00:00&issued=lt2024-04-23T00:00:00
We currently generate two CTE's in SQL and then join them. This is inefficient and can be improved if we combine the two conditions into one CTE.

Related issues

Addresses [issue AB#121039].

Testing

Manually tested against the example query. All other automated tests run for regression testing.
