build(deps): add opentelemetry bom and tracing dependencies

Replace micrometer-tracing-bridge-brave with the full OpenTelemetry stack
(bridge-otel, OTLP exporter, SDK, trace SDK, propagators, API, context).
Add OTel BOM and semconv to the parent POM for centralized version control.
Add OTel API dependencies to dc3-common-rabbitmq and dc3-common-facade-grpc
for trace context propagation.
