 - `POST /api/ui-upload` - Web UI file upload

-- Network bandwidth
-- Disk I/O
-- Processing time
-- Storage space

-- `POST /api/process/` - Trigger document processing
-- `POST /api/send_to_dropbox/` - Send to Dropbox

-- `POST /api/send_to_onedrive/` - Send to OneDrive

-- `POST /api/send_to_all/` - Send to all destinations
-- `POST /api/processall/` - Batch process all files
-- `POST /api/azure/process/` - Azure OCR processing
-- `POST /api/openai/extract-metadata/` - OpenAI metadata extraction
-
-**Rationale**: These endpoints trigger:
-- External API calls (OpenAI, Azure)
-- CPU-intensive operations (OCR, PDF processing)
-- Network requests to cloud storage
-- Background Celery tasks
