ADFA-3418: Tie IDEEditor's EventBus registration to its window

IDEEditor registered with the default EventBus in initEditor() and unregistered only in release(), which a recreate (dark mode, locale) never reaches, so EventBus kept each open editor and the destroyed activity (426 KB in a LeakCanary dump after the breakpoint-listener path was fixed). Register on attach and unregister on detach, as CodeEditorView does.

Chosen over closing editors on recreate: close() posts DocumentCloseEvent through an async dispatcher, which could reach the language server after the recreated activity reopens the same file.
