fix: AI photo enhance modal stays open with result preview; fix basicsr build

- Modal no longer auto-closes after Real-ESRGAN completes; result loads into
  canvas so user can review, adjust sliders, and choose to apply or discard
- Backend skips swapEntryPhotoFiles until user confirms via Применить
- New DELETE /api/entries/:id/photo/enhance-ai/preview for temp file cleanup
- photo-ai Dockerfile: patch basicsr via find+sed instead of import (avoids
  torchvision.functional_tensor import crash)
