style(wishlist): Sortierung als Pill-Chips wie auf der Startseite

Das native <select> fiel stilistisch aus dem App-Bild. Jetzt
identisch zur "Alle Rezepte"-Sortierung auf der Startseite: drei
grüne Pill-Chips (Beliebteste / Neueste / Älteste), aktive Pille
invertiert. Verhalten gleich, nur die Optik angepasst.
