FastAPI service for PDF Trainer (pdf upload/download + send-config + notify-unknown).

## Save configuration email

When the Trainer UI calls `POST /api/send-config`, the API stores the JSON config and (optionally) emails a confirmation
with the config JSON + original PDF attached.

Set these env vars on the **pdf-trainer-api Space**:

- `PDF_PIPELINE_PIPELINE_NOTIFY_TO` (recipient email for confirmations)
- `PDF_PIPELINE_NOTIFY_FROM` (must be the same Gmail account you OAuth’d)
- `GMAIL_CREDENTIALS_JSON` + `GMAIL_TOKEN_JSON` (paste full JSON contents; or use `PDF_PIPELINE_GMAIL_CREDENTIALS_JSON` / `PDF_PIPELINE_GMAIL_TOKEN_JSON`)
