fix: resolve accept, reset, and cancel buttons in image section editing

Fixed image section editing button functionality:

1. **getCurrentEditingSectionId fix**: Updated to recognize both text editor containers
   (.ui-edit-editor-container) and image editor containers (.ui-edit-image-editor-container)

2. **Accept button fix**:
   - Properly handles alt text updates with immediate DOM reflection
   - Calls acceptChanges() and hideEditor() directly instead of generic handler
   - Ensures updateSectionContent() is called for immediate visual feedback

3. **Cancel button fix**:
   - Directly calls cancelChanges() and hideEditor() for proper flow
   - Removes dependency on generic handler that couldn't identify image containers

4. **Reset button fix**:
   - Calls resetSection() and refreshes image editor with reset content
   - Provides immediate visual feedback by reopening editor with original content

Added comprehensive test suite with 7 tests covering all button interactions.
All image section editing buttons now work correctly.
