fix(ui): HUD layout pass — resolve overlapping elements (#792)

- HUD status panel moved to y=80 (below TimeDisplay at 16-70)
- Removed redundant time row from HUD (TimeDisplay handles it)
- Debug overlay starts at y=150 (below HUD status panel)
- Stance indicator moved below minimap (y=192, was overlapping at y=16)
- Interaction prompt moved to y=-240 (above dialogue box at -200)
