deleteAll() only clears the Doctrine store; the page-tree index is keyed on
md5(dirs + folderHash + config->checksum() + lang) (Pages::buildRegularPages).
With cache.check.method:folder a freshly-created entry could survive in that
index and stay invisible to GET /api/v1/pages{route} (404), so opening a
just-posted entry for editing showed "this entry no longer exists" ~2/3 of the
time. Add Cache::invalidateCache() (touches system.yaml -> bumps config
checksum) so the index key changes and the tree rebuilds next request. Chosen
over clearCache('standard'), which would nuke compiled Twig + assets on every
post. Fixes the create->edit round-trip (Playwright ES1) and the DEL1 flake.
