fix: Multi-distro LXC container fixes for autologin and package installation

- Rocky/AlmaLinux 10 (EL10): Version detection for DNF 5 with correct packages (langpacks-en instead of glibc-langpack-en), makecache refresh, fallback to minimal install
- openSUSE: Install ncurses-utils and terminfo-base, set TERM in /etc/profile.d and /etc/environment to fix 'unknown terminal type'
- Gentoo: Fixed template pattern to use underscore (-openrc_) instead of dash, special version handling
- openEuler: Set privileged container (var_unprivileged=0) to workaround PVE setup hook limitation
- Devuan: Enhanced sysvinit autologin with multiple inittab patterns, fallback console entry, telinit reload
- CentOS/all: Updated URLs from raw.githubusercontent.com to git.community-scripts.org
- General: Better error handling and removed duplicate code blocks
