I think we should also change https://github.com/open-contracting/credere-backend/blob/main/app/routers/statistics.py to not check the database and calculate and return the statistics instead

And then we could delete the update_statistics commands and Statistics table...

Sure, but let's do that in another PR, this one is a big changeset already.

delete the ... Statistics table

The table does keep a history of statistics as of each date – not sure if this was a requirement.

Okay to merge on my end.
