fix: centralize OPENVINO_PROVIDER_CONFIG and log SystemExit

Address Sourcery review feedback on PR #1879:

- Move OPENVINO_PROVIDER_CONFIG from _onnx_enhancer.py to
  platform_info.py (a leaf module with no modules.* imports), so
  the enhancer and face_swapper no longer import each other just to
  share a constant. _onnx_enhancer re-exports it; face_swapper now
  imports it at module top level instead of inside get_face_swapper().
- Narrow run.py's SystemExit handling: catch SystemExit separately
  and print a [startup] message so the failure is visible instead
  of being swallowed alongside ImportError/FileNotFoundError.
