Upgrade frontend toolchain to latest majors

Bump React 19.2, Relay 21, React Router 8, Vite 8 with
@vitejs/plugin-react 6, ESLint 10, GraphQL 17, TypeScript 6,
@types/node 24, and Tailwind 4.3 across the workspaces.

vite-plugin-react 6 (Vite 8) no longer runs Babel, so the Relay
tagged-template transform now runs through @rolldown/plugin-babel
in the console and trust Vite configs.

Relay 21 ships first-party types and enables the ambiguous-alias
check by default; disable that flag to preserve existing queries
and add explicit usePreloadedQuery type arguments where the new
types no longer infer the operation. TypeScript 6 deprecations and
stricter inference are addressed in tsconfigs and call sites.

Keep n8n-node on ESLint 9 and eslint-plugin-react on 7.37.5, the
newest releases compatible with their toolchains.
