refactor(server/utils): create reusable utilities for various story-related functions

`bodyHandler` takes a request body and returns the chapter content as a string
`formChapterTransform` serializes a chapter-like object supplied in a request body to an actual
	proper chapter object
`getBucket` retrieves the story content gridfs bucket
`replaceGridFS` either creates or updates (deletes + reuploads) a gridfs file
