fix(deps): Pin openai<2.0 and migrate to uv

The langfuse fork requires openai 1.x - the beta.chat module was
removed in openai 2.x causing import errors.

Changes:
- Pin openai to 1.78.1 (compatible with langfuse fork)
- Update constraints to openai>=1.44,<2.0
- Migrate Dockerfile from pip to uv for faster builds
