feat(lieferung/neu): PDF upload with SSE streaming and result dialog

- Add PDF-Upload button to ManifestHeader (delivery forms only)
- New ManifestPdfDialog: live SSE event log, structured basedata,
  and line-items table streamed from POST /api/delivery/parsePDF
- ApiClient.delivery.parsePdfSse: multipart/form-data upload,
  async generator yielding typed SSE events (status, llm_call,
  tool_call, usage, progress, result, error)
- ManifestForm.handlePdfUpload: drives SSE generator, updates
  dialog state in real-time; dialog opens immediately on upload
- Fix MUI icon imports (CheckCircle, ErrorOutlined)
