refactor(server/utils): add transformer for regular chapter objects

Browse Source 
this transforms a story object into a slightly different object to be served by the api. notable differences are the `totalChapters` field and the removal of the `chapters` array. `chapters` is then replaced by a `currentChapter` object, representing the currently "selected" chapter, with an added `text` field
