filemanager: consider using cargo-lambda-cdk instead of aws-cdk-lambda

[mmalenic]

This project is more up to date and maintained than the current aws-cdk-lambda that filemanager uses. It also seems to have slightly simpler configuration, so we should investigate whether it's worthwhile to switch.

cargo-lambda-cdk also supports bundling the Lambda code using docker, which is convenient for CodeBuild because there is no requirement to install Rust or cargo lambda.

@brainstorm might be able to remove those query_* files by using the before command hook to run the local database when building with cargo-lambda-cdk: https:/cargo-lambda/cargo-lambda-cdk?tab=readme-ov-file#command-hooks
