Omada - AVX-only support

Discontinue support for non-AVX CPUs in Omada installation scripts, exiting with an error if AVX is not detected. Simplify Java installation by using a setup_java function and remove manual Azul Zulu Java installation steps. Update default Omada version from 13 to 12 in scripts and JSON config. Replace manual cleanup steps with cleanup_lxc.
