fix(build.func): generalize OS version fallback for all distros
Refactor fallback_to_debian12() into fallback_to_previous_os_version() which dynamically determines the previous major version for any OS type (debian, ubuntu, alpine, fedora, rocky, centos) by scanning available local and online templates. The 3-option menu in the LXC stack upgrade prompt now shows for all OS types, not just Debian 13.
