fix: ensure accept, cancel, and reset buttons properly close image editing UI

Fixed critical UI closure issue in image section editing:

1. **Root Issue**: The `hideEditor()` method was not removing editor containers from DOM,
   causing editing UI to remain visible after button clicks

2. **hideEditor() Enhancement**:
   - Now properly removes both `.ui-edit-editor-container` and `.ui-edit-image-editor-container` from DOM
   - Ensures complete UI cleanup when editors are closed
   - Handles cases where no containers exist gracefully

3. **Button Behavior Fixes**:
   - **Accept**: Saves alt text changes, accepts changes, and closes UI completely
   - **Cancel**: Discards changes and closes UI completely
   - **Reset**: Resets to original content, updates display, and closes UI completely
   - All buttons now provide immediate visual feedback with complete UI closure

4. **Reset Button Logic Fix**:
   - Removed reopening of image editor after reset (was keeping UI open)
   - Now properly closes UI and shows reset content in display mode
   - Provides better user experience with clear completion feedback

Added comprehensive test suite with 7 tests covering DOM manipulation and UI closure.
All image editing buttons now behave consistently with proper UI cleanup.
