Merged PR 4763: Align metrics within KPIs report

# Description

There's misalignment in the different areas in the business, but even within our own report...

**I'm not saying this is perfect** - but at least it forces a common Data Glossary within Main KPIs. I'd suggest later on reviewing naming - same as we need to do for revenue anyway -, but for the meantime, at least have consistency on our side.

Changes:
* Est. Billable Bookings -> Billable Bookings. We have other metrics stated as Estimated in the Data Glossary.
* Waiver and Resolutions payments to host are now called Payouts. This is not perfect but at least is clear we're paying out, so it's a cost.
* Host Resolutions Payment Rate is now explicitly mentioning how it's being computed to avoid confusion with the Payout Rate, that does not appear here yet, but appears in the YTD.

Additional Changes:
* Tests are also aligned with new names.
* Re-order booking display, so Cancelled Bookings (inclusion and exclusion) are shown below. Having them the first is weird.
