Refactor and clean up codebase by removing unused functions and reorganizing imports

- Removed unused model keys and functions from properties.py.
- Deleted projection.py as its functions were no longer needed.
- Cleaned up model_catalog.py by removing unused model directory function.
- Updated imports in various test files to reflect new module structure.
- Removed deprecated test cases related to image editing tools.
- Added new tests for ONNX runtime provider selection logic.
