Several sude/*.json schedules can exist on disk; only one runs at a time, chosen by a client Load. Sud no longer takes a path at all - it starts empty (EMPTY_SUD) and the server config no longer names a specific schedule file, removing the implicit link to sud_0010.json in particular. Reading/writing sude/*.json is now entirely the client's job (e.g. the GUI's Load/Save file dialogs); the server's Sud only ever holds whatever was last Load()ed, in memory, until replaced or the server restarts. Updates demo_sud.py/demo_sud_save_load.py to construct an empty Sud() and load() a schedule explicitly, matching the new constructor.
