ci: add service host discovery and strict policy docs validation

- Add multi-candidate host discovery (localhost, host.docker.internal, gateway) in api-endpoint-tests
- Pass discovered service host via AITBC_API_HOST environment variable to test script
- Update test_api_endpoints.py to use AITBC_API_HOST for all service URLs
- Add validate-policies-strict job to docs-validation workflow for policy Markdown files
- Add job names to package-tests matrix for better CI output clarity
- Add --import
