The e2e test was hardcoded to navigate to `http://127.0.0.1:3344` instead
of using the configured `baseURL` in `playwright.config.ts` which points
to the Vite dev server (`http://localhost:5173`). This caused tests to
fail with `net::ERR_CONNECTION_REFUSED`.
This commit replaces the hardcoded URL with `/` so that Playwright
correctly uses the `baseURL` setting. It also updates the title assertion
to include "星火应用商店".
