Adding code so eicr always flows to augmentation

[robertandremitchell]

Description

This adds a new passthrough logic to ttc-lambda to ensure that all eICR flow to AugmentationEICRV2/. This is necessary for APHL to pick up the eICR regardless of it needed augmentation and some uncovered exceptions.

ended up falling a little bit back into the e2e rabbit hole, as this change does impact (positively!) some "brittleness" I noticed/encountered on the last e2e ticket where augmented eicrs were getting tripped up because they didn't have any data needing augmenting. Now that we expect more eicrs to fully run end to end, I changed some of the logic there to reflect that. I can make that set of work a sub-branch of this ticket, if we prefer to review those two pieces of work separately.
