Previously, the new topic button in the Horizon theme's sidebar hardcoded its la…bel and icon, so plugins like
discourse-calendar could not relabel it (e.g. to "New Event" in an events category) even though the button outside the sidebar updated correctly.
This change runs the label and icon through the `create-topic-label` and `create-topic-icon` value transformers,
matching core's `d-navigation` behaviour so plugin overrides apply in the sidebar too.
Since this button can now have two states, the icon is brought back to improve quick-glance clarity.
