update .env.example to include BRANDO_API_KEY and MINIO_ENDPOINT

feat: migrate ComfyUI nodes from presigned URLs to Brain API storage endpoints

## Core Architecture Changes
- Add new BrainApiClient for direct Brain API communication
- Replace presigned URL workflow with storage_id/filename pattern
- Update MediaStreamInput to use storage_id + filename instead of presigned_download_url
- Update MediaStreamOutput to use storage_id + filename instead of presigned_upload_url

## Brain API Client Implementation
- Add comprehensive BrainApiClient with authentication and error handling
- Implement get_presigned_upload_url() and get_presigned_download_url() methods
- Add proper Bearer token authentication for Brain API requests
- Include environment variable configuration for Brain API endpoint and credentials

## Media Stream Node Updates
- Refactor MediaStreamInput to request presigned URLs from Brain API using storage_id
- Update MediaStreamOutput to upload directly to MinIO using Brain API presigned URLs
- Simplify node interface by removing presigned URL inputs from workflow templates
- Update JavaScript frontend to hide system inputs and manage node UI state

## Infrastructure Improvements
- Add .idea/ to .gitignore for IDE file exclusions
- Update user_input.py to use new storage_id pattern
- Streamline web interface JavaScript for cleaner node management
