Service: Should fail build when mandatory information is missing.

[TomCools]

Describe the bug
I was able to build the service, without build error, despite not filling in the application properties (timefold.application.version=v1), which led to a vague error reported here: #2391

Expected behavior
If required information is not available at build time, fail the build. This includes this property as well as potential other properties.

Actual behavior
Doesn't fail the build, leading into unexpected errors.

To Reproduce
See reproducer for #2391

Not a blocker for now, @TomCools will document but we will improve validation on this.

Implemented in #2429 - the Quarkus build now fails fast with a clear error when the mandatory timefold.application.version property is missing.
