fix: parallel execution dependency graph for exec, start_service, stop_service

[mattevans]

Description

• exec, start_service, and stop_service now call ProducesService() in the dependency graph
• Previously these instructions mutated service state without declaring it, so store_service_files on the same service could race with a preceding exec in --parallel mode
• Updates dependency graph test expectations to match

Error:

kurtosis run --enclave your-enclave-name --image-download missing --args-file multi-client.yaml --parallel --parallelism 10 .

Is this change user facing?

YES - fixes race conditions when using --parallel
