feat(aggregation-api)!: add new endpoint for economy/mc-all aggregation

[mabw-rte]

Context:
for the aggregation apis, we want to add additional endpoints that perform aggregation on the folder economy/mc-all

I don't see the part concerning the regex for column names (see JIRA issue).
You should add and test it.
Also, for mc-all, there are new type of files that can be requested (see JIRA issue) so you need to implement that.

I didn't read everything but overall the code is super complex and it's really hard to understand your logic so could you add some doc inside the code to make it more readable and maintainable.

We must not merge this before making sure the API breaking change is intended and documented in the changelog.
