Remove remaining problematic module-level addon access

- Remove module-level addon variable in kodi_utils.py
- Load addon locally in add_menu_directory_item() where needed
- Load addon locally in SHOW_SETTINGS mode in functions.py
- Keep __addon__ fallback in functions.py for non-critical uses (__addondir__, addon_id, PLUGINPATH) which have safe fallback values
- loghandler.py already has proper exception handling around __pluginpath__ usage
