chore(GODT-2848): Simplify User Event Service

Browse Source 
Rather than having the services subscribe to each individual event type,
have only one subscriber for the whole event object. This spreads the
logic to the service through the `EventHandler` type.

This is important for the next stage where the IMAP service will be
required to apply events from the past.
