fix: bundle certifi CA per SSL su Windows/macOS + bump v1.8.5

- requirements.txt: certifi come dep esplicita
- main.py: setta SSL_CERT_FILE/REQUESTS_CA_BUNDLE su certifi.where() al boot
- build_windows.py + build_macos.py: --collect-data certifi nel PyInstaller

Bugfix: senza certifi bundlato, le chiamate HTTPS dal build Windows
falliscono con CERTIFICATE_VERIFY_FAILED (attivazione licenza impossibile).
