Caret differentiated + Accent-Hover wie in Elemente

User:
1. Wireframe-Caret war fast draussen (zu weit rechts), bei anderen
   minimal mehr rechts erwartet
2. Hover-Effekt mit accent-border wie in Elemente fuer alle Pills

Fix 1: backgroundPosition differenziert:
- Ohne Gear: 'right 10px center' (normaler Pill-Rand-Abstand)
- Mit Gear: 'right 1px center' (klebt am Gear)
So sitzt der Caret optisch konsistent — bei Display innen, bei den
anderen direkt vor dem Gear.

Fix 2: Hover-Akzent analog ElementeApp PillButton:
- BarCombo Pill-Container: bg → bg-item-hover, border → accent
- BarButton (Camera, Settings-Gears in Pills, Print-Toggle): selbe Logik,
  active-State bleibt accent-fill
- View-Toggle-Buttons: bg → bg-item-hover, text → accent-light, active
  bleibt accent-fill
Transitions 0.15s fuer smooth feel.
