merge main f13c60c into feat/voice-outlines

reconcile voice outlines with main f13c60c, retaining German/Japanese,
Operator HUD retirement and Context/Radio cleanup, named-building
containment, courtyard-hole, non-Latin identity, attribution, cancellation
and antimeridian repairs

keep outline callouts above the open voice preview when an above-panel
slot fits without colliding with another callout,
and clip the compact dock location label on narrow screens
