BOHA 6147131aad chore(deps): upgrade React 18.3 -> 19.2.7 ...

react / react-dom 18.3.1 -> 19.2.7; @types/react 18.3.31 -> 19.2.17;
@types/react-dom 18.3.7 -> 19.2.3 (latest stable 19.2.x).

Only breaking change hitting our code: React 19 removed the no-arg useRef<T>()
overload. AppShell's logoutTimer -> useRef<T | undefined>(undefined) — the same
transform the official `types-react-codemod preset-19` (useRef-required-initial)
applies. No other preset-19 transforms were relevant (already on createRoot; no
ReactDOM.render, string refs, propTypes/defaultProps on function components).

No Next.js / RSC in this project (it's a Vite SPA served by Fastify), so those
React 19 concerns don't apply here. MUI v7, framer-motion 12, TanStack Query 5,
react-router-dom 6 and react-quill-new all installed cleanly against React 19
(no peer-dependency conflicts).

Gates: tsc 0 | build 0 | vitest 247/247 | eslint 0 errors.
