Adds a self-contained "Create Transfer" flow to the mobile app, reachable from a new dashboard tile. Lets a warehouse user scan a product or bin, pick an inventory item, enter a quantity, choose a destination bin, and complete the transfer.

Summary

• New dashboard tile Create Transfer opens a 4-step flow:
  • Entry - scan product or bin barcode, or search via the modal.
  • Item list - candidate InventoryItem rows (product · bin · lot · qty) filtered by the resolved product/bin, with a debounced filter input.
  • Quantity - read-only context panel + numeric input capped at the inventory item's quantityNotPicked.
  • Destination - destination bin scan/search, then submit.
  • Complete - one-tap PUT to flip the PENDING transfer to COMPLETED, success morphs the button to "New Transfer".
