refactor: remove deploy.cmd and update Dockerfile for health checks

- Deleted the deploy.cmd script as it was no longer needed.
- Updated Dockerfile to include curl for health checks and added a non-root user for improved security.
- Modified health check command to use curl for better reliability.
- Adjusted docker-compose.test.yml to reflect changes in health check configuration.
- Cleaned up appsettings.json and removed unused configuration properties.
- Removed Resource entity and related requests from the codebase as part of the architectural shift.
- Updated documentation to reflect the removal of hardware binding and related endpoints.
