the go toolset container supports go 1.24 now:

https://catalog.redhat.com/software/containers/ubi9/go-toolset/61e5c00b4ec9945c18787690

we should update to use this container and update the project to use 1.24

This would involve updating  zest, yummy, and tang as well as the backend.

Update go.mod and the Dockerfile in the backend
and the go.mod file in the other repos.
