Use --kickstart-uri during factory restore

This change updates the factory auto-restore install process to use the
newly introduced --kickstart-uri option, allowing the installer to use
the miniboot.cfg file from the factory backup directory.

It also fixes an issue where the factory restore playbook failed to
detect the registry backup file due to the factory backup being named
factory_backup.tgz instead of following the default
*_platform_backup_*.tgz pattern. The fix sets the
registry_backup_filename variable to correctly handle the factory
backup naming.

Test Plan:
01. PASS - Run a factory restore and verify that the miniboot.cfg
    stored in the subcloud at /opt/platform-backup/factory/
    <sw_version>/miniboot.cfg is used during the installation.
02. PASS - Run a non-factory auto-restore and verify that it still uses
    the miniboot.cfg from the miniboot image.
03. PASS - Run a factory restore and verify that the restore playbook
    correctly uses the image registry backup file.
