Fixes the CI checks that have been failing on main since #6, so that #8 and later PRs can go green.

• Code analysis: ran lint:fix and prettier:fix. The remaining fixes were done by hand:

  • declared __webpack_nonce__ as a global in the patched injectStylesIntoStyleTag.js
  • marked the intended console calls in middleware.js and razzle.extend.js with eslint-disable-next-line no-console, as ContentSecurityPolicy.jsx already does
  • added injectStylesIntoStyleTag.original.js to .eslintignore and .prettierignore. It's the unpatched style-loader copy kept for comparison, so it stays as it is.

  The rest is formatting only, plus import/first moving the require below the import in src/index.js.

• Changelog check: yarn install --immutable failed because yarn.lock still had the @plone/volto peer range as ^17.0.0, while package.json says ^16.0.0 || ^17.0.0. The lockfile is refreshed.

• Acceptance: GitHub fails the job before it starts because it uses the retired actions/upload-artifact@v3. It's moved to v4.

lint, prettier and stylelint pass locally in the addon-dev container (Volto 17.0.0). The unit test run finds no tests.
