FBA Planning reserved quantity columns and inventory updates

Four new reserved quantity columns added to FBA Planning, plus unrounded Raw Inventory values and a new Market Intelligence metric.

Several product changes shipped together.

seller_inventory_fba_planning: Four new reserved quantity columns have been added:

Reserved FC Transfer
Reserved FC Processing
Reserved Customer Order
Reserved Staging

A calculated column reserved_including_transfer has also been added as the sum of all four above. This exists because for some marketplaces Amazon includes FC Transfer in the reserved_quantity column (Amazon-IN, Amazon-SA, Amazon-AE, Amazon-BR, Amazon-AU), while for all other marketplaces it does not.

Documentation update: Two new pages added to give customers guidance on:

FBA Planning dataset: Use this for FBA stock
All Listings dataset: Use this for FBM

Raw Inventory FBA & Raw Inventory FBA History: price and per_unit_volume are no longer rounded.

Market Intelligence Dashboard: Added Rank Score (1/BSR) for easier aggregation and trend tracking.
