fix: Use uv run for all test commands in CI

The GitHub Actions environment uses uv to manage dependencies, but the
Makefile was calling python3 directly. This caused "No module named pytest"
errors. Now all test targets properly detect and use uv when available.

- Updated all test targets to use uv run when available
- Falls back to python3 -m for environments without uv
- Fixes CI failures across all test jobs
