fix: Pin scipy<1.14 to fix reverse_geocoder import error

- Pin scipy<1.14 in requirements.txt (scipy 1.14+ has PyInstaller bundling issues)
- Add SciPy hidden imports to backend_server.spec for compatibility

Fixes: 'ModuleNotFoundError: No module named scipy._cyutility'
which was causing backend to crash on macOS.
