QoL: easier item transfer to crates

[Dowlgrett]

As of 1.20.7, transferring items into crates requires first moving them to the hotbar and then using Shift + Right-Click to transfer the entire stack. This works fine for a few items, but when handling large amounts—like stacks of rocks—it quickly becomes tedious. Players have to repeatedly move stacks from their inventory to the hotbar, disrupting their setup, then shift-click them one by one, then starting over for how many stacks they have.

A simple quality-of-life improvement would be allowing players to drag and drop entire stacks directly from the inventory into crates, making bulk storage much more convenient.
