"""One table of generic Bambu filament ids, complete for every generic Bambu has.

A PP spool without a preset was sent to the printer with tray_info_idx=""
because the shared table had no PP row, while the Configure dialog's own copy
did (#3273). The copies are gone; these tests keep the table complete.
