Force LSKF in ConfirmCredential UI when pending escrow token exists

Escrow tokens can only be activated by user confirming their LSKF,
while ConfirmCredential allows both LSKF and biometrics by default.
By requiring LSKF, it simplifies the DPC's flow of requesting the user
to activate a pending escrow token.

This change tweaks the ConfirmCredential UI to skip biometrics if pending
token exists.
