feat: Live cookie banner overlay in SDK — auto-open + FAB reopen button
- CookieBannerOverlay: opens automatically on first visit (localStorage check)
- CookieBannerFAB: shield icon button at right-[10rem] to reopen settings
- 3 consent modes: accept all, reject all (nur notwendige), custom settings
- 4 categories: Notwendig (locked on), Statistik, Marketing, Funktional
- Category toggles with descriptions in settings view
- Datenschutzerklaerung + Impressum links in banner
- Consent persisted to localStorage, custom event fired on change
- Comprehensive Playwright E2E tests (16 tests):
- First visit auto-open, button visibility, category toggles
- Accept all / reject all / custom settings persistence
