Klaro polish: remove redundant toggle-all text, responsive button rows, real per-service descriptions

- Empties Klaro's own "Mit diesem Schalter..." boilerplate under the
  modal's per-service toggle-all switch — redundant next to a plainly
  labeled switch.
- .cn-ok/.cn-buttons/.cm-buttons now explicit flex-wrap rows (side by
  side until they genuinely don't fit, then wrap) instead of relying
  on Klaro's own fragile inline-block flow.
- Every tracking-codes provider gets a real description in the modal's
  service list (was title-only) — what it does and, where publicly
  documented and stable, the actual cookie names/lifetimes (_ga/
  _ga_<container-id> for GA4, _fbp/fr for Facebook Pixel). GTM/Maps
  descriptions are deliberately non-specific about exact cookies —
  neither has a fixed, publicly enumerable list.
