fix(korrespondenz): larger empty state text, hide divider+chips when no history
- Icon: 36px (was 24px), heading text-xl font-black (was text-sm)
- Subtext: text-base (was text-xs), max-w-sm (was max-w-[280px])
- Search button: h-10, text-sm, full max-w-sm width (was fixed 260px)
- Recent persons divider and chip block moved inside the {#if recentPersons.length > 0}
block so no blank "oder" section renders when localStorage is empty
- Chips: text-sm px-4 py-2 (was text-xs), avatar h-5 w-5
