Implement comprehensive testing framework and enhance documentation

- Add Project-Tests directory with complete testing infrastructure
- Create main test runner with JSON reporting and categorized tests
- Implement system validation tests (RAM, disk, network, permissions)
- Add security testing for HTTPS enforcement and deployment methods
- Create unit tests for framework functions and syntax validation
- Add ConfigValidation.sh framework for pre-flight system checks
- Enhance documentation with SECURITY.md and DEPLOYMENT.md guides
- Provide comprehensive testing README with usage instructions

The testing framework validates system compatibility, security configurations,
and deployment requirements before execution, preventing deployment failures
and providing clear error reporting for troubleshooting.
