fix(apple/iOS): inline-large header — title and action circles share the bar row

The home screen stacked the toolbar row above the large title; the modern (iOS 26
Liquid Glass) header puts the large title leading and the glass action circles trailing
on the SAME row. That's exactly .toolbarTitleDisplayMode(.inlineLarge) — applied on iOS
only, macOS keeps its window chrome untouched.

Verified in the iPhone 17 simulator: "punktfunk" large title left, gear/+ circles
right, one row.
