Update frontend to React 19 (#22275)

remove unused RecoilRoot and fix implicit ref callback

Remove the vestigial recoil dependency (zero consumers) and convert the implicit-return ref callback in SearchView to block form to prevent React 19 interpreting it as a cleanup function.

replace react-transition-group with framer-motion in Chip

Replace CSSTransition with framer-motion AnimatePresence + motion.div for React 19 compatibility (react-transition-group uses findDOMNode). framer-motion is already a project dependency.

migrate react-grid-layout v1 to v2

Replace WidthProvider(Responsive) HOC with useContainerWidth hook
Update types: Layout (single item) → LayoutItem, Layout[] → Layout
Replace isDraggable/isResizable/resizeHandles with dragConfig/resizeConfig
Update EventCallback signature for v2 API
Remove @types/react-grid-layout (v2 includes its own types)

upgrade vaul, next-themes, framer-motion, react-zoom-pan-pinch

vaul: ^0.9.1 → ^1.1.2
next-themes: ^0.3.0 → ^0.4.6
framer-motion: ^11.5.4 → ^12.35.0 (React 19 native support)
react-zoom-pan-pinch: 3.4.4 → latest

upgrade to React 19, react-konva v19, eslint-plugin-react-hooks v5

Core React 19 upgrade with all necessary type fixes:

Update RefObject types to accept T | null (React 19 refs always nullable)
Add JSX namespace imports (no longer global in React 19)
Add initial values to useRef calls (required in React 19)
Fix ReactElement.props unknown type in config-form components
Fix IconWrapper interface to use HTMLAttributes instead of index signature
Add monaco-editor as dev dependency for type declarations
Upgrade react-konva to v19, eslint-plugin-react-hooks to v5

upgrade typescript to 5.9.3
modernize Context.Provider to React 19 shorthand

Replace <Context.Provider value={…}> with across all project-owned context providers. External library contexts (react-icons IconContext, radix TooltipPrimitive) left unchanged.

add runtime patches for React 19 compatibility

Patch @radix-ui/react-compose-refs@1.1.2: stabilize useComposedRefs to prevent infinite render loops from unstable ref callbacks https://github.com/radix-ui/primitives/issues/3799
Patch @radix-ui/react-slot@1.2.4: use useComposedRefs hook in SlotClone instead of inline composeRefs to prevent re-render cycles https://github.com/radix-ui/primitives/pull/3804
Patch react-use-websocket@4.8.1: remove flushSync wrappers that cause “Maximum update depth exceeded” with React 19 auto-batching https://github.com/facebook/react/issues/27613
Add npm overrides to ensure single hoisted copies of compose-refs and react-slot across all Radix packages
Add postinstall script for patch-package
Remove leftover react-transition-group dependency

formatting
use availableWidth instead of useContainerWidth for grid layout

The useContainerWidth hook from react-grid-layout v2 returns raw container width without accounting for scrollbar width, causing the grid to not fill the full available space. Use the existing availableWidth value from useResizeObserver which already compensates for scrollbar width, matching the working implementation.

remove unused carousel component and fix React 19 peer deps

Remove embla-carousel-react and its unused Carousel UI component. Upgrade sonner v1 → v2 for native React 19 support. Remove @types/react-icons stub (react-icons bundles its own types). These changes eliminate all peer dependency conflicts, so npm install works without –legacy-peer-deps.

fix React 19 infinite re-render loop on live dashboard

The “Maximum update depth exceeded” error was caused by two issues:

useDeferredStreamMetadata returned a new {} default on every render when SWR data was undefined, creating an unstable reference that triggered the useEffect in useCameraLiveMode on every render cycle. Fixed by using a stable module-level EMPTY_METADATA constant.
useResizeObserver’s rest parameter ...refs created a new array on every render, causing its useEffect to re-run and re-observe elements continuously. Fixed by stabilizing refs with useRef and only reconnecting the observer when actual DOM elements change.
