Move the sanitizer next to the directory helpers so the CLI download command and the daemon honour use_username_dirs too, not only the TUI. Resumed downloads keep the folder they were saved with instead of nesting the username a second time, and toggling the setting applies to the next download without a restart. Document the config key.
