fix: update CSV reporter tests for new Repository and Assessment validation

- Repository now requires paths to exist and be git repos
- Assessment now requires config parameter and proper fields
- Updated all fixtures to create real git repos with subprocess
- Added missing Assessment fields (config, discovered_skills, metadata, schema_version)

Note: Some CSV tests still failing due to findings validation requiring
findings count to match attributes_total. These are pre-existing issues
on this branch that need separate investigation.
