Add regression E2E test to verify PWA pull-to-refresh is disabled

[martinezharo]

Motivation

• Prevent Chromium's pull-to-refresh gesture from interfering with the installed mobile PWA by ensuring overscroll-behavior-y: none applies when running in display-mode: standalone.
• Add regression coverage so changes to the stylesheet can't accidentally re-enable the gesture.

Description

• Add a Playwright E2E test in e2e/smoke.spec.ts that inspects document.styleSheets and verifies a @media (display-mode: standalone) rule sets overscroll-behavior-y: none for html, body.
• Keep the existing stylesheet src/app/pwa.css (which contains the @media (display-mode: standalone) rule) and rely on the test to detect regressions.

Testing

• Ran the focused Playwright test: pnpm exec playwright test e2e/smoke.spec.ts --project=chromium --grep 'installed PWA disables', which passed.
• Ran ESLint on the modified test file with pnpm exec eslint e2e/smoke.spec.ts, which returned clean results for the change.
• Ran the full unit test suite with pnpm test, which completed successfully (13 files, 146 tests passed).
