Add GTM snippet #107
Description
Adding this GTM snippet will serve both for #78 and the need for frontend error capture, by letting us deploy an update to the frontend once and then manage adding/removing frontend embeds from Google's console. The price for this is letting Google collect all the data about all the things, but they were going to do that anyway if we're adding GA.
