LeoVasanko d3e2196c83 Localization (#1)
Implement comprehensive content localization, admin panels for editing each language, AI translation interface with automatic updates when base language version is changed.
- SEO tags for all language URLs
- Uses accept-language by default, ?lang=en overrides temporarily
- User edits patched on top of translations
- RTL language supportReviewed-on: #1

// Structure tab: the draggable site structure tree. Focusing a page's row
// navigates to it in place (no transitions). Close and tab switching live
// in EditorShell.
//
// The tree comes from the server nested (GET /_api/pages); every node is
// real — a label with a title and slug, with content (landing page) or
// without (category whose URL renders a placeholder page). The front page
// is a top-level row with an empty slug, not the parent of the others.
//
// Languages: the LangSelect switches which language the TITLES are shown
// and edited in (rows without a translation show the original, dimmed) —
// the selection is shared shell-wide (./editorLang) with the page editor
// and the page preview. Translated title edits write a per-language
// fragment (POST /_api/structure with lang); the structure itself —
// slugs, order, hierarchy — is language-independent and always edits the
// same tree.
