7558aeb5e6 fix: sync DB sessions in Celery, letterbox YuNet, dedupe detections
- Rewrite all vision tasks to use sync psycopg2 sessions instead of
  asyncpg — fixes 'another operation in progress' and event loop errors
  when Celery forks workers sharing the async connection pool
- Letterbox-pad images to exactly 640x640 for YuNet face detector
  (was crashing on non-square thumbnails)
- Deduplicate object detections per label per photo — keep highest
  confidence only to avoid photo_tags PK violation on multiple
  detections of the same class
- Add all queues (-Q default,high,low,vision) to worker command

9282a5c734 feat: add vision pipeline scaffolding with ONNX backend
Introduce the app/services/vision/ module with ABC interfaces, ONNX
Runtime backend, model registry, and per-task implementations:
- OpenCLIP ViT-B/32 embedder (image + text, 512-d)
- RapidOCR engine (PP-OCRv4 via ONNX, no PaddlePaddle)
- YOLOv8n object detector (raw ONNX, no ultralytics runtime)
- YuNet + SFace face processor (Apache 2.0, opencv_zoo, 128-d)
- DBSCAN face clustering helper

Add VisionSettings to config (mulita.yml + Pydantic), bootstrap_models.py
for first-boot weight downloads, models_data Docker volume, and ROCm
backend stub for future GPU acceleration.

No Celery tasks wired yet — models load but nothing invokes them.
