Now we will display count of valuations as "Number" on Valuations list and Valuation Preview while making Purchase Order. This feature will allow users to identify which valuation in a row is being previewed.

Important: When deleting valuations, number of valuations will be recalculated to show on UI correct count of valuations and keep numerical order, which means that if we have valuations 1,2,3,4,5,6, and we deleted valuation number 3, then valuations numbers will be recalculated to 1,2,3,4,5. Edit valuation number option is blocked.

Exporter: The default cell for the Number is C8. As an admin, to change the cell, add     "valuation_number_cell": "cell_ID" to the advanced template config.
