Add coverage for DBM dynamic_service mode

[amarziali]

Motivation

Add coverage for the new DD_DBM_PROPAGATION_MODE=dynamic_service value that combines service mode behaviour with automatic SQL base hash injection, without requiring users to separately set DD_DBM_INJECT_SQL_BASEHASH=true.

Setting dynamic_service is equivalent to:

DD_DBM_PROPAGATION_MODE=service
DD_DBM_INJECT_SQL_BASEHASH=true

The test checks that the basehash is the same in both the ddsh comment field and the related span meta _dd. propagated_hash

Note: already tested working locally with the in progress java implementation: DataDog/dd-trace-java#11432
