fix(UVE): Ensure Window Object Re-Initialization in UVE iframe

[rjvelazco]

This pull request includes several changes aimed at improving the functionality and testing of the EditEmaEditorComponent in the core-web library. The key updates involve refactoring the iframe URL handling, enhancing the test coverage, and improving the inline editing feature.

Refactoring and Improvements:

• Updated the iframe src binding to use uveStore.$iframeURL() instead of $editorProps().iframe.src in edit-ema-editor.component.html.
• Refactored the setIframeContent method to include an enableInlineEdit parameter and moved the inline editing script handling to a new method handleInlineScripts in edit-ema-editor.component.ts. [1] [2]

Testing Enhancements:

• Added event listener and dispatcher methods to the iframe mock in edit-ema-editor.component.spec.ts to simulate iframe load events.
• Modified multiple test cases to dispatch iframe load events and verify the iframe content in edit-ema-editor.component.spec.ts. [1] [2] [3] [4] [5]

Store and State Management:

• Introduced a new computed property $iframeURL in the withEditor store to dynamically generate iframe URLs, including handling traditional pages by returning about:blank. [1] [2] [3] [4] [5]
• Removed the src property from the EditorProps interface as it is now handled by the computed $iframeURL.

Code Cleanup:

• Removed unnecessary requestAnimationFrame calls and related code from edit-ema-editor.component.ts. [1] [2]
• Cleaned up unused imports and reorganized utility function usage in withEditor.ts.

These changes collectively enhance the maintainability, functionality, and testability of the EditEmaEditorComponent.
