CnWizardDialog

Multi-step modal with per-step slots, back/next navigation, optional per-step validation, and a single result phase. Each step is declared in the steps[] prop ({ id, label, optional?, icon? }) and rendered via a #step-{id} named slot with the navigation API exposed through the slot scope.

Use CnFormDialog for single-step forms, CnRichSubmitDialog for single-step submit-with-files flows, and CnExportWizard for the specific scope+format+delivery export-trigger shape.

Slot scope

Each #step-{id} slot receives:

Field	Type	Description
`next`	`() => Promise<void>`	Run validation + advance to the next step.
`back`	`() => void`	Step back. No validation.
`jumpTo`	`(stepId) => void`	Jump to any step. No validation.
`submit`	`() => Promise<void>`	Run validation + emit `@submit`.
`currentStep`	`Object`	The current step definition.
`stepIndex`	`number`	Zero-based index of the current step.
`totalSteps`	`number`	Total number of declared steps.
`stepData`	`Object`	Shared cross-step data.
`setStepData`	`(partial: Object) => void`	Merge `partial` into `stepData`.
`isFirst`	`boolean`	True on the first step.
`isLast`	`boolean`	True on the last step (Next → Submit label flip).
