Merged PR 3239: Decommission Verification Payments V1

# Description

Decoms verification payments v1 version, and keeps v2 alive. The PBI of Guest Payments (Biz Overview) was already switched to V2 but the exposures was not reflecting it, so I changed this. Then I dropped all v1 models for verification payments and their entries in schema.

# Checklist

- [X] The edited models and dependants run properly with production data. I did run the upstream dependencies on V2 and I don't see orphans in my dbt docs. However I did not fully run end-to-end all models up to PBI reports since there's other sources involved (Xero, etc).
- [X] The edited models are sufficiently documented.
- [X] The edited models contain PK tests, and I've ran and passed them.
- [NA] I have checked for DRY opportunities with other models and docs.
- [NA] I've picked the right materialization for the affected models.

# Other

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