/**
 * Extended Playwright test fixture with FrigateApp.
 *
 * Every test imports `test` and `expect` from this file instead of
 * @playwright/test directly. The `frigateApp` fixture provides a
 * fully mocked Frigate frontend ready for interaction.
 *
 * The fixture also installs the error collector (see error-collector.ts).
 * Any console error, page error, or same-origin failed request that is
 * not on the global allowlist or the test's `expectedErrors` list will
 * fail the test in the fixture's teardown.
 *
 * CRITICAL: All route/WS handlers are registered before page.goto()
 * to prevent AuthProvider from redirecting to login.html.
