Harden UI layout for font scale and long strings

- Measure and cap the HUD target chip after each font-scale change; clip HUD top labels.
- Ellipsize long action-button labels so panels cannot grow past the viewport.
- Add accessibility/button layout assertions and refresh the gallery captures.
- Record the font/layout pass in TODO, docs, changelog and memory.
