Merged PR 2865: Propagate tax exclusive check in hero payments

# Description

This PR propagates tax exclusive check in hero payments for the reporting of Check in Hero.
Additionally, it keeps propagating the amounts with tax inclusiveness in case, at some point, we need them. These are with the new naming convention.

In order not to break anything, the previous amounts are duplicated and aliased in reporting.

Lastly, I spent some time adding some clarifications and documenting payments set to currency and the dependant used for check in hero.

# Checklist

- [X] The edited models and dependants run properly with production data.
- [X] The edited models are sufficiently documented.
- [X] The edited models contain PK tests, and I've ran and passed them.
- [X] I have checked for DRY opportunities with other models and docs.
- [X] I've picked the right materialization for the affected models.

# Other

- [ ] Check if a full-refresh is required after this PR is merged.
