Pull request overview

This PR refactors task management and storage paths across the codebase. It adds task metadata exposure via Flower API integration, consolidates helper functions, and reorganizes output file storage paths.

• Adds task_info field to all response schemas (images, videos, texts, workflows) to expose task metadata from Flower
• Refactors context classes to use nullable task_id parameters and extracts get_output_path methods for better code organization
• Reorganizes output file storage to use feature-based directory structure (e.g., images/model/ instead of just model/)
