feat(pry): production readiness pass — apify actor, async db, retry wiring, tests, observability, mypy

Browse source 
- Pin Dockerfile --workers 1

- Wire retry.py + circuit breakers into ultimate_scraper tiers

- Add Apify actor (apify_actor.py, Dockerfile.apify, .actor/actor.json)

- Add async SQLAlchemy support alongside sync db.py

- Add 31 HTTP integration tests (tests/test_api_integration.py + test_api_mcp.py)

- Add OTLP exporter support in observability.py

- Re-enable mypy var-annotated error code; fix annotations

- Improve CI workflow (pip cache, install -e .[dev], gitleaks, commitlint, 40% coverage gate)
