Update Vite React config to match Vite 8.0.6 template

[anonpay-sh]

This PR updates the Vite React config to match the Vite 8.0.6 template (https://github.com/vitejs/vite/blob/v8.0.6/packages/create-vite/template-react-ts/tsconfig.app.json), which is currently the latest version.

Here's what changed and why:

• "target": "ES2022" was changed to "target": "es2023".
  • This aligns with the newer default browser targets in Vite 8 (https://vite.dev/guide/migration#default-browser-target-change).
• "useDefineForClassFields": true was dropped.
  • useDefineForClassFields has been true by default for targets of ES2022 and higher since TypeScript 4.3 (https://www.typescriptlang.org/docs/handbook/release-notes/typescript-4-3.html#usedefineforclassfields-now-defaults-to-true-on-esnext-and-eventually-on-es2022).
• "lib": ["ES2022", "DOM", "DOM.Iterable"] was changed to "lib": ["ES2023", "DOM"].
  • The ES2022 library was changed to ES2023 to align with the target change.
  • The DOM library now includes DOM.Iterable as of TypeScript 6.0 (https://www.typescriptlang.org/docs/handbook/release-notes/typescript-6-0.html#the-dom-lib-now-contains-domiterable-and-domasynciterable), so the latter can be dropped.
• "module": "ESNext" was changed to "module": "esnext".
• "types": ["vite/client"] was added.
  • types now defaults to [] in TypeScript 6.0 (https://www.typescriptlang.org/docs/handbook/release-notes/typescript-6-0.html#types-now-defaults-to-), and this is the preferred way to make Vite's client types available in user code according to the documentation (https://vite.dev/guide/features#client-types).
• "strict": true was dropped.
  • strict is now true by default in TypeScript 6.0 (https://www.typescriptlang.org/docs/handbook/release-notes/typescript-6-0.html#simple-default-changes).
• "noUncheckedSideEffectImports": true was dropped.
  • noUncheckedSideEffectImports is now true by default in TypeScript 6.0 (https://www.typescriptlang.org/docs/handbook/release-notes/typescript-6-0.html#simple-default-changes).
