Prepare for avoiding full page reloads: move entity type and ID from base path and into routing parameters

To do so I need to refresh the page by moving to a new URL and re-mounting the editor. That is because the entity type and ID are part of the base path for the editor. It is entirely contextual to one entity.</p> <h3 id="proposed-resolution">Proposed resolution</h3> <p>Have <code>/xb</code> be the base path and the editor has the entity type and ID as part of its routing. This will break a lot of things, probably, like moving to /editor or /preview, etc. But maybe the useNavigation hook can simplify this by always using the entity type and ID and a different hook for changing the main entity being edited.</p> <h3 id="ui-changes">User interface changes</h3> > Related issue: [Issue #3529836](https://www.drupal.org/node/3529836) > Related issue: [Issue #3546163](https://www.drupal.org/node/3546163)
