On /ru/onlineboard/SU6272-20260418 the document title was blank and the
meta description carried a literal '{{ flightNumber }}' placeholder.
Two root causes:
1. Translation values carried Angular ngx-translate syntax {{ var }} but
the React app uses i18next-icu (single-brace {var}). Interpolation
never fired, so SEO strings served as-is. Rewrite every {{ var }}
(and {{var}}) occurrence to {var} across ru/en locales.
2. <SeoHead> was rendered inside the lazy-loaded OnlineBoardDetailsPage.
The SSR response streams the Suspense fallback before the lazy
bundle resolves, so <title>/<meta> never land in the <head>. Move
SeoHead to the route page (src/routes/.../page.tsx) where it
renders synchronously from URL-derived data, and drop the inner
duplicate. Add buildFlightDetailsSeoFromId for the URL-only path.
formatDateForSeo now handles both 'yyyyMMdd' (URL) and
'yyyy-MM-dd' (API) so both entry points produce '18.04.2026'.
3. React 18 doesn't auto-hoist <title> inside body to document.head —
add a useEffect in SeoHead that also writes document.title on the
client. SSR still emits the <title> element for crawlers.
