ROOT CAUSES IDENTIFIED:
1. GlobalAIPrompt template had unescaped JSON braces that broke Python's .format()
- Python treats {...} as placeholders, causing KeyError when rendering
- Escaped JSON braces to {{...}} while preserving {title}, {content}, {max_images}
2. Image functions hardcoded aws-admin IntegrationSettings which didn't exist
- Functions failed when aws-admin account had no IntegrationSettings
- Added GlobalIntegrationSettings fallback for all missing values
CHANGES:
- Fixed GlobalAIPrompt.image_prompt_extraction template in database (escaped JSON)
- Updated generate_image_prompts._get_max_in_article_images() with fallback
- Updated generate_images.prepare_data() with fallback for all image settings
- Updated tasks.process_image_generation_queue() with fallback for config + API keys
TESTED: Template rendering now works, GlobalIntegrationSettings.max_in_article_images=4
