fix(otel): use mergeServiceFiles path instead of include for Shadow 9.x

Shadow 9.x's ServiceFileTransformer strips the `inst/` prefix when using
`include("inst/META-INF/services/*")`, placing merged service files under
`META-INF/services/` instead of `inst/META-INF/services/`. This breaks
the OTel agent's classloader which expects isolated services under `inst/`.

Using `path = "inst/META-INF/services"` preserves the correct output path.

Also add missing `duplicatesStrategy = DuplicatesStrategy.INCLUDE` to
console-otlp, log4j2, and console-opentelemetry-noagent shadow JARs
so that mergeServiceFiles and Log4j2 transformers can see duplicates
before they are deduplicated.
