Introduced a typed and flexible dialog infrastructure: * Added new base classes (`DialogData`, `DialogData<TResult>`) to support asynchronous and strongly-typed dialog results. * Implemented Alert, Prompt, and custom Component dialogs, including their respective option classes and dedicated Razor components. * Updated `DialogService` to manage a generic dialog collection and expose new methods for alert, prompt, and custom dialogs. * Refactored dialog resolution to a generic `Resolve<TResult>` pattern with centralized closing logic and improved backdrop handling. * Introduced `DialogOptions`, `DialogOpenOptions`, the `DialogSize` enum, and the `DialogResult` type. * Added a reusable `DialogHeader` component for standardized dialog headers. * Improved overall extensibility and reusability of the dialog system.

…er angry on this docs
…, and fix review issues
- BbDialogProvider: reuse Primitives escape-keydown.js stack for proper
Escape handling (respects PreventClose, blocks AlertDialog dismiss)
- BbDialogProvider: add focus trap via IFocusManager and scroll lock via
portal.js lockBodyScroll when dialogs are active
- BbDialogProvider: wire up DialogSize from ComponentDialogData.Options
to dynamic container classes (was dead code in ComponentDialog)
- BbDialogProvider: implement IAsyncDisposable, properly dispose JS
module references (portalModule, escapeModule)
- BbDialogProvider: use correct ARIA role (alertdialog for Alert/Confirm,
dialog for Prompt/Component)
- ComponentDialog: remove dead GetWidth() method
- DialogService: fix XML docs on obsolete Confirm() method
- DialogOptions: fix ConfirmText XML doc default value ("OK" not "Continue")
- DialogDemo: add View Code sections for Form, Nested, Non-Dismissible demos
- DialogDemo: add selected-value labels to nested dropdown controls demo
- DialogDemo: add comprehensive API reference for all dialog sub-components,
DialogService methods, option types, and IDialogReference
- Update API surface snapshot
