As a product manager, I want exports per day to be added to the stats page for Wikisource, so that I can track potential changes or growth in a project that I want to monitor.
Background: We would like an easier way to see how ebook export activity may grow over time, especially after our work to improve the WS Export tool. One way to do this is to add exports per day to the statistics page
Acceptance Criteria:
- Add the ability to see ebook exports per day (or at least over a period of time) in ws-export stats
