AFT-726: Enable defaults for ftag GNN in the trigger

This is an extension of !73628 (merged), where I enable the same feature in the trigger and add default values specific to trigger taggers.

This causes one change in trigger outputs which should have no effect on the trigger counts: since I added a non-zero default value for many of the GNN outputs, the previous default values (which were added in cases where no tracking was run) have changed. These jets were vetoed in the trigger hypo anyway though, so it should change nothing.
