Support the 02.08.04 Bambu Network Plug-in Series

The 02.08.02 series appended queue_plate_id to PrintParams and nothing
after it changed the ABI OrcaSlicer calls, so adding the field brings
the current layout up to 02.08.04. Make 02.08.04 the latest series and
drop 02.08.01 from the whitelist: its PrintParams no longer matches, and
its malformed bind table is refused by dyld on macOS 27, so it cannot
load there. A stored 02.08.01 falls back to the latest series through
the existing unsupported-version path.
