Merged PR 2615: Beautification of KPIs dimensions

# Description

Changes:

* Separate 1) the internal naming of dimensions available within DWH vs. 2) the display of the dimensions in the reporting. Mainly it changes the "by_number_of_listings" to display "By # of Listings Booked in 12 Months". I edited the production macro since to me it's linked to when things are available for display.
* Add preceding zeros on the segmentation so it's ordered correctly. Before, the segment 21-60 was displayed before the 6-20.
* Also added some capital letters to the schema config of the reporting model :)

I attach a screenshot of how it looks in PBI in my local development branch to exemplify why this is "Beautification". Be aware that merging this also puts in production the dimensions.
