Refactor Omada install and improve repo suite mapping

Refactored omada-install.sh to use setup_java and setup_mongodb functions, simplifying Java and MongoDB installation logic. Improved manage_tool_repository in tools.func to provide explicit suite mapping and fallbacks for newer or unknown Debian and Ubuntu releases, enhancing compatibility with future distributions. Minor comment translations and cleanups included.
