ui/console: unregister console from QOM tree on close
Call object_unparent() in graphic_console_close() to remove the console from /backend/console[N]. This drops the QOM tree reference, while the initial object_new() reference keeps the console alive for potential reuse. When graphic_console_init() reuses a closed console, re-register it in the QOM tree.
