Merged PR 3431: Adds Invoicing metrics

# Description

Same old story: includes all metrics coming from Xero.
Adds a daily model, monthly, mtd + monthly agg and mtd agg
A test to compare values new vs. old
AND fixes the issue I mentioned with the timestamp - an issue in the old KPIs.

# 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.
- [NA] I have checked for DRY opportunities with other models and docs.
- [X] I've picked the right materialization for the affected models.
