Honor noMcGaPermissionsWithClientPin by routing mc and ga to built-in UV or failing clearly instead of minting a clientPin token. Drive a change-PIN flow when forcePINChange is set before acquiring a PIN-based token. Normalize collected and new PINs to Unicode NFC and check the minimum length in code points while keeping the 63-byte UTF-8 maximum.

The PIN flow ignored authenticator policy and measured PINs in bytes. This routes operations away from a PIN token when the device forbids it, drives a required PIN change first, and normalizes PINs to NFC with the minimum length checked in code points.
Closes #256.
