Marcel 64d27d6d61 feat(ocr): per-sender model registry and /train-sender endpoint ...

engines/kraken.py:
- Add _SenderModelRegistry with LRU eviction (max configurable via
  OCR_MAX_CACHED_MODELS env var), double-checked locking, invalidate(),
  and path whitelist (/app/models/ only)
- Add _load_sender_model() helper for testability
- extract_page_blocks() and extract_region_text() accept optional
  sender_model_path; route to sender registry when provided

models.py:
- OcrRequest gains senderModelPath: str | None = None field

main.py:
- /ocr and /ocr/stream pass request.senderModelPath to Kraken engine
- New /train-sender endpoint: validates output_model_path, runs ketos
  train with base model as starting point, invalidates sender cache

docker-compose.yml:
- Add OCR_MAX_CACHED_MODELS: "5" to ocr-service environment

test_sender_registry.py:
- 4 tests: cache hit, LRU eviction, invalidate, path traversal guard
