PolyStorage

Bedrock fixes. Shift-click quick transfer no longer desyncs for Bedrock players: the server resends the full container state after every storage move, so Geyser's client-side prediction is corrected instantly instead of bouncing items. Search and craft-amount entry now open a native Bedrock form (a real text dialog) for Bedrock players instead of the Java anvil screen, which never worked through Geyser. A cancelled form changes nothing, and the terminal redraws safely afterward. Java players are completely unchanged. The form dialogs need Geyser running on the server itself; on proxy setups without it, Bedrock players keep the old behavior. The optional Bedrock Support Pack is attached again as an extra file and is unchanged from 1.2.0.
