Refactor Dockerfile to use uv sync with upstream pyproject.toml

Replace fragile system site-packages copying with uv's native project
management. The previous approach hardcoded Python paths which broke
when packages installed to different locations.

Changes:
- Use uv sync with upstream pyproject.toml instead of uv pip install
- Use venv at /app/.venv instead of copying system site-packages
- Move tempio download to final stage where it's actually used
