Fix TypeError: customImages is not iterable

- Fixed updateImageCount() function to handle new customImages data structure
- Added compatibility for both old (array) and new (object) customImages format
- Function now properly handles { task: [], consequence: [] } structure
- Prevents TypeError when toggling image enabled/disabled states

Error was occurring when:
- User clicked checkbox to enable/disable images
- updateImageCount() tried to spread customImages as array
- But customImages was object with task/consequence properties

Fix ensures compatibility with both data formats for smooth migration.
