refactor(evals): split test cases into tests/*.yaml files

Move inline test cases from promptfooconfig.yaml into separate files
organized by category (core.yaml, governance.yaml). Main config now
uses file://tests/*.yaml glob pattern per promptfoo best practices.

This makes it easier to add new test categories without bloating the
main config, and lets contributors add cases by dropping new YAML
files into tests/.
