* Rename import_local_ip to get_local_ip Replaces all references to the helper function import_local_ip with get_local_ip across scripts and documentation for consistency. Updates usage examples and comments to reflect the new function name. * Rename get_local_ip to get_lxc_ip and update usage Replaces all references to get_local_ip with get_lxc_ip across scripts, documentation, and templates for clarity and consistency. Updates the implementation in core.func to improve IP detection for LXC containers, and adjusts helper functions in addon scripts accordingly.
