Pull request overview

This PR refactors the WebView in-app support to use a proper layer-based architecture instead of relying on payload string parsing. The changes move WebView configuration from being a separate top-level PayloadDto type to being a layer type (WebViewLayer) within ModalWindowDto, which is then mapped to InAppType.WebView at runtime.

Changes:

• Removed PayloadDto.WebViewDto and PayloadBlankDto.WebViewBlankDto classes, consolidating WebView as a layer type
• Added WebViewLayerValidator and WebViewParamsDeserializer to properly validate and deserialize WebView layers
• Updated InAppMapper to convert ModalWindows with WebViewLayer to InAppType.WebView
• Fixed a bug where SnackbarDto was incorrectly assigned MODAL_JSON_NAME type constant
• Removed getWebViewFromPayload method from InAppMessageViewDisplayerImpl as WebView handling now occurs at the DTO level

• This test class is now empty except for setup and teardown. The Gson mock is created but never used. Consider either removing this test file entirely if no tests are needed, or removing the unused Gson mock from the setup if tests will be added later.
