Fix MQTT status parsing: handle integer CurrentStatus

MQTT printers send CurrentStatus as an integer (e.g., 1) while WebSocket
printers send it as a list (e.g., [1]).

Changes:
- Updated ElegooMachineStatus.from_int() to wrap integer in list and call from_list()
- Updated PrinterStatus.__init__() to detect format and call appropriate method
- Cleaner separation: from_int wraps and delegates to from_list

This fixes the TypeError: object of type 'int' has no len() error that was
preventing status updates from MQTT printers.
