🐛 Fixed browser back button behaviour after clicking "x posts" on tags screen (#1306)

closes https://github.com/TryGhost/Ghost/issues/11057

- removed static "replace" configuration of posts/pages query params
- used the router service to register a `willTransition` event handler which handles conditional replaceState transition behaviour only when filters are changed whilst already on the posts/pages route
