Fix #368
Fix #384
Fix part of #369
This change ensures that completed progress is consistent and correct everywhere for fractions and ratios topics. It also ensures that there are thumbnails defined for chapters, and that all thumbnails are consistent regardless of which screen topics, stories, or chapters are viewed from. It updates the reported lesson count to be correct (before we were displaying canonical story count rather than total exploration count).
Verified domain tests pass after fixes. No new tests were added since most of the new code is temporary. There's some logic we may share, and that code has TODOs to track adding tests for it in future work.
