fix(text): Sync text color with theme highlight color in pressed state

When ToolButton is in pressed (isSunken) state, the icon already changes
to the theme highlight color, but the text remains unchanged. This causes
inconsistent visual feedback between the icon and text.

Now both icon and text use palette().highlight().color() in pressed state,
providing a unified user experience across all theme modes.
