Subject: [PATCH] refactor: replace remaining raw os-release checks with
 get_os_info helpers

- inventree: use get_os_info id for ubuntu check
- jellyfin: use get_os_info id for intel dependency path
- nginxproxymanager: use get_os_version_major for pcre package switch
- frigate: use get_os_version_major while keeping Debian 12 requirement
