fix: Pass complete SQS event to offline queue consumer

[seb-cr]

Our current offline SQS event payload contains only the message body. This is insufficient in applications where we need to inspect the metadata of received messages, and leads to TypeError in the consumer during testing.

This PR adds the missing fields to the event, trying to be relatively accurate. For example, the source queue ARN includes the correct queue name and AWS account ID. In terms of overall structure, an SQSEvent type is helpfully provided in the @types/aws-lambda package, which I've used to ensure our mocked event meets expectations.

Complete event samples can be found here for reference: https://docs.aws.amazon.com/lambda/latest/dg/with-sqs.html

This all looks ok to me.

Sidenote: I'm not thrilled about the alai library. Maybe I misunderstand it but it looks like a single line of code, and the name is not memorable or descriptive. Perhaps just me, though.

Oh, but it is both memorable and descriptive, once you've seen it: AWS Lambda Account ID

We love acronyms at CR don't we? 😁

In all seriousness though, I agree; we should probably alias the import so that the actual function identifier is something meaningful like getAccountIDFromARN. I'll happily approve a PR for that if you fancy creating one.
