ITX Plan de Envío

- New product movement flow: Moving a single product now takes you through a step-by-step flow. Select the destination cycle, review the product (image, GMN, MCC, campaign, description, and estimated stock), check the destination cycle, then confirm. If a product can't be moved, you'll see a validation message before you continue.
 - Change a product's collection while moving it: When the calendar is grouped by Collection, you can optionally choose a destination collection while moving a product. This updates its cycle and collection in one step.
 - Group details screen now follow calendar filters: Collection, presentation and set detail screens now automatically apply your active calendar filters, so they match what you see in the calendar.
 - More accurate +N indicator: The +N indicator now appears only when shipping criteria is applied, in both the Period Header and the Collection summary screen. Each product in its breakdown is counted only once, under its highest-priority reason.
