#**Context:** UI Action API spec: define UI Actions [sys_ui_action] to enhance interactivity and customization in user interfaces. UI Actions include buttons, context menu items and related links on forms and lists. Use the dedicated `UiAction` construct for cleaner, type-safe UI Action definitions.
