Page context menu: Purge from SSR cache

SsrPurgeItemProvider adds the item behind Clear cache for real pages (doktype < 199) whenever the purge endpoint is configured. The callback module posts the page uid to the new vitec_ssr_purge_page ajax route, which resolves the page path through the site router, purges it via SsrPurgeService (trigger contextmenu:username, logged as usual) and reports back as a toast notification.
