Overview

Sync subscriber for Events::KitComponentChanged.

Re-runs the cheap half of Item::KitConsolidator#consolidate_all_fields
inline: qty and COGS only. Product pages, inventory UI, and fulfillment
checks read these fields in the request cycle so they must be fresh
before the publishing transaction's caller returns.

The expensive half (consolidate_weights_and_dimensions, which calls
Item::ShippingBoxCalculator and is combinatorial in component count)
is owned by KitWeightsDimensionsHandler and runs async.

Subscribes to: Events::KitComponentChanged
