fix(browser): clear browsing data via BrowserProfileUtils

Desktop clearBrowsingData was stuck because QML WebEngineProfile has no
cookie API and the old clearCache path threw before the fallback timer.
Add BrowserProfileUtils (QtWebEngine-only) to clear HTTP cache + cookies,
and align the QML API with the UI (clearBrowsingData / clearSiteData).
