sp system & task

Phase: v2

sp system

System-wide key/value config.

Subcommand	Method	Path
list	GET	/api/system/config/list
get <key>	GET	/api/system/config/query/{key}
save	POST	/api/system/config/save
delete <key>	DELETE	/api/system/config/delete/{key}

sp task

Scheduled tasks (console + storage variants).

API	Path
Console list	GET /api/scheduledTask/list
Storage CRUD	/api/config/scheduledTask (add, modify, run, …)

CLI should document which backend path is used per subcommand when implemented.
