require Certificate Transparency via Network Security Config

There is a new security feature that is easy to enable when running on Android 16+

• https://developer.android.com/privacy-and-security/security-config#CertificateTransparencySummary

See the transparency logs here:

• https://crt.sh/?q=amazonaws.com
• https://crt.sh/?q=f-droid.org
• https://crt.sh/?q=github.com
• https://crt.sh/?q=githubusercontent.com
• https://crt.sh/?q=github.io
• https://crt.sh/?q=gitlab.com
• https://crt.sh/?q=gitlab.io

I'm not sure how to test this otherwise.
