ci(fix): resolve test failures in CI/CD pipeline

- Fix path to isql command in database initialization scripts
- Add SPARQL_UPDATE role assignments to SPARQL account
- Set permissions for 'nobody' user in both dataset and provenance databases
- Update both bash and PowerShell scripts for cross-platform compatibility

This resolves the test failures in the GitHub CI/CD pipeline by ensuring
proper database permissions and access for test operations.
