Updated the `ContentTemplate` to enhance the layout of the `#attachment-content` container by using `display: flex` and ensuring full height utilization. Added CSS rules for consistent styling of the `.CodeMirror` editor, including font size and height adjustments. Simplified CodeMirror initialization for XML files by removing redundant `<textarea>` creation and directly embedding the editor. Added `viewportMargin: Infinity` for better rendering and used `setTimeout` to ensure proper sizing and refresh. Refined plain text rendering for non-XML files to maintain a clean and consistent display.
