Pull request overview

Updates this AMQP adapter package to align with recent yiisoft/queue message API changes, primarily around the new serializer namespace and the shift from data/metadata to payload/meta in message handling, plus aligning middleware-related tests with the current Queue construction API.

Changes:

• Migrated usages of JsonMessageSerializer to MessageSerializer + JsonMessageEncoder, and updated MessageSerializerInterface import namespace.
• Updated test message helpers/handlers and tests from getData()/getMetadata() + fromData() to getPayload()/getMeta() + fromPayload().
• Adjusted middleware integration test queue construction to pass the default queue name and middleware definitions via constructor.
