fix(tests): capture window.open URL before redirects in clickOpenWebApp

Some wallets' webapp_link points to URLs that immediately redirect to
external services (e.g. MathWallet's webapp_link is chromewebstore.google.com
which redirects through consent.google.com, dropping the ?uri= query param).

Reading lastTab.url() after a 500ms timeout races against these redirects,
making the wallet-features.spec.ts:131 "open web app wallet" test flaky on CI.

Patch window.open in the page context to capture the URL synchronously at
call time, before any navigation/redirect happens.
