Hannah Wolfe bb3cc8c0f8 Reimplement custom theme templates (#8147)
closes #8082

- Update the `pickTemplate` logic to
  a) rely on getActive().hasTemplate() instead of being passed a list of paths
  b) support the concept of a fallback, which is returned if there is no theme, or if the theme doesn't have a more specific template
- Update every instance of template picking, across the 3 internalApps, and render-channel, to use this new logic
- update the tests
