Title: Add store transaction logs to CSV export & points remaining report to coach reports 

1. Fix https://github.com/learningequality/ka-lite/issues/2492 by adding an option to export store transaction logs
2. Fix https://github.com/learningequality/ka-lite/issues/2493 by adding a simple 'points remaining' coach report

@aronasorman Should be reviewable/mergable now if in a rush, but still on TODO list:

* add tests for simple coach report
* add tabular report navigation bar to store log coach report
* add a 'detail view' for store transaction logs (when clicking on student, show what they have purchased in a detailed coach report
