feat(ui): Adressen, Retoure, Suche und Cookie-Hinweis

- Adressen im Zweierraster, Standardadresse mit Honigrahmen und Wabenmarke,
  neues Adressformular in der Formular-Karte
- Retoure: Positionen als Liste mit Waben, Formular in der Karte
- Suche: Vorschlaege gleiten gestaffelt herein, Suchbegriff hervorgehoben,
  Lupe wird zum Schliessen-Symbol; das Feld legt sich ueber die Navigation
  statt sie zu verschieben (vorher: waagerechter Scrollbalken)
- Cookie-Hinweis als schwebende Karte; "Nur notwendige" und "Alle
  akzeptieren" gleich gewichtet (vorher war Akzeptieren Waldgruen auf
  Waldgruen und kaum als Knopf erkennbar)
