- Add exact: true to all language button selectors in lang.spec.ts to
prevent Playwright from matching "Abmelden" (contains "de") alongside
the DE language button
- Fix goto in conversations applyFilters to use absolute path
/conversations?... instead of relative ?... so URL updates correctly
- Set locale: 'de-DE' in playwright.config.ts so Accept-Language header
is consistent and locale detection defaults to German during tests
