We'll use $bsonSize projection to get the document size and map it to a document card in the crud document list:

• We will only do this if there is no custom projection provided by the user
• We will add {doc: "$$ROOT", size: {$bsonSize: "$$ROOT"}} projection to the find call
• When receiving the document, map doc to the HadronDocument and store the bson size value as a symbol on the hadron doc
• The value can then be used to render the insight in the document list
