chore: build the visual reporter with Vite 6

[plum117]

Summary

First step of the visual reporter upgrade: build the reporter with Vite 6 (5.4 → 6.4).

Remix 2 accepts Vite ^5.1.0 || ^6.0.0, so Vite 6 is possible before the move to React Router. Replaces Dependabot #1267, which changed only package.json and not pnpm-lock.yaml (a frozen install would fail).

Vite is a development dependency of the reporter: it builds the static report UI (build/client), which the CLI copies and serves. Users do not install Vite.

Planned next steps (one PR each)

Remix 2 accepts only React 18, so the order is:

1. Vite 6 (this PR)
2. Remix 2 → React Router 7 (accepts React 18/19, Vite 5–8, TypeScript 5/6; also removes the TypeScript 6 peer warning)
3. React 19 (replaces chore(deps-dev): bump react and @types/react #1264)
4. Vite 8 and vite-tsconfig-paths 6 (replaces chore(deps-dev): bump vite from 5.4.21 to 8.3.3 #1263)

Test

• The built UI is pixel-identical: the demo report (pnpm build + pnpm script:prepare.report, served with sirv) opened in headless Chrome with WebdriverIO, screenshots of the home view and of the comparison overlay (click on the first snapshot): 0 different pixels between the Vite 5 and the Vite 6 build.
• GitHub Pages build (GITHUB_PAGES=/visual-testing/): the asset paths keep the base path.
• Reporter typecheck, pnpm test (lint, types, 1077 unit tests): pass.
• The build messages are the same as before (the Remix "future flags" notes and a sourcemap note for SelectHeader.tsx, both already there with Vite 5).

No changeset: development dependency only, and the built UI does not change.
