meteor3: React 16 -> 18.3 with createRoot

Browse source 
react/react-dom ^18.3.1 (--legacy-peer-deps for the pinned ancient react-*
libs, which still work on 18 via legacy context but gate React 19). Client
entry uses createRoot. Browser-verified on / and /fires; REST smoke
byte-identical (12/12).
