Initial commit: yourdev-session-pki package

Debian package for PKI-based session authentication with Orange AD.
- Direct PKINIT auth via pam_exec + kinit (bypasses SSSD certmap)
- GDM smartcard login with SafeNet eToken / Thales
- Automatic Kerberos TGT via PKINIT
- Compatible with orange-yourdev-login package
