ArcaneAlertDialog class

A stateful alert dialog widget that handles the internal layout and animations for Arcane dialogs.

ArcaneAlertDialog is the core stateful component behind ArcaneDialog, managing dynamic layout for headers (leading, title, content, trailing) and actions. It integrates with Arcane's ModalContainer for bordered, rounded surfaces and supports keyboard-aware padding via AnimatedPadding. This class ensures responsive, theme-consistent modals, serving as the rendering engine for all Arcane dialog variants like Command, Confirm, Date, and more, within the broader UI overlay system.

Key features:

• Flexible row-based header with conditional flexible sizing for content.
• Actions row with invisible spacer for alignment and scroll handling.
• Theme-scaled gaps and border radius (borderRadiusXxl).
• Centered presentation with bottom inset handling for keyboards.
• Blur-in animation inherited from parent.
