Unseal when items are removed but the pocket isn't emptied

[RenechCDDA]

Summary

Bugfixes "Crafting will unseal containers when contents are removed"

Purpose of change

• Closes sealed can remains sealed after using contents in recipe #68923

item::on_contents_changed() only unseals when the pockets are emptied.

Describe the solution

Specifically track the item we're taking out, making sure to unseal the specific pocket containing that item, regardless if it empties the pocket. (It is at least mod-wise possible for items to have multiple pockets with independent sealed status and/or containing different items)

Describe alternatives you've considered

item::use_charges has an alternative implementation(below), but it's buried in a lambda.
