chore(deps): Update MetaMask design system and React to v18

[sirtimid]

Summary

• Update @metamask/design-system-react from ^0.1.0 to ^0.6.0
• Update @metamask/design-system-tailwind-preset from ^0.5.0 to ^0.6.1
• Update @metamask/design-tokens from ^8.0.0 to ^8.1.1
• Update react and react-dom from ^17.0.2 to ^18.3.1
• Update @types/react and @types/react-dom to v18
• Update @testing-library/react from ^12.1.5 to ^16.3.0 (removes need for separate @testing-library/react-hooks)
• Update @radix-ui/react-slot to 1.2.4 (removes the yarn patch)

Code changes for React 18 compatibility

• Use createRoot API instead of deprecated render in popup entry points
• Explicitly type children prop in TableHeader component (React 18 no longer includes children implicitly in React.FC)
• Update test imports from @testing-library/react-hooks to @testing-library/react
• Update Vite config for React externals (function-based approach)

Test plan

• yarn build passes
• yarn test passes (3338 tests)
• yarn test:e2e:ci passes (45 e2e tests across extension, nodejs, omnium-gatherum)

Note

Updates the UI stack to React 18 and the latest MetaMask design system, with necessary code/test and build config changes.

• Upgrade react/react-dom (and types) to ^18.3.1; update @metamask/design-system-react ^0.6.0, @metamask/design-system-tailwind-preset ^0.6.1, @metamask/design-tokens ^8.1.1
• Replace react-dom render with react-dom/client createRoot in extension and omnium-gatherum entrypoints; update corresponding tests
• Migrate tests from @testing-library/react-hooks to @testing-library/react; tweak expectations and use renderHook from RTL
• Kernel UI: explicitly type children in TableHeader, update peer deps to React 18, refine Vite externals for React, and Vitest config adds aliases/dep optimizer includes
• Remove Yarn patch by resolving @radix-ui/react-slot to 1.2.4
• Adjust repo coverage thresholds and refresh lockfile accordingly
