Add internal notifications to notification drawer

- previously only a curated list of API Events made it into the drawer
- this change catches all "internal events" currently experienced as toasts & brings them into the drawer
- future improvement may be to suppress the "toast" for certain internal events so as not to
  excessively message the user
