Migrates the hand labeler to the new attack chain

[Toastical]

What Does This PR Do

Fixes #27356
Migrates the hand labeler to the new attack chain
Adds a QoL examine for the state of the labeler (remaining labels and label text)
Allows you to put the labeler in a backpack if there's no label
Special thanks to @DGamerL, @Adrer for helping out with signals and the old attack chain and to @warriorstar-orion for help with the new attack chain!

Mostly LGTM, but I'd like to confirm what happens with storages (e.g. backpacks). This is slightly busted before this PR:

• When on, sets a label on the storage.
• When off, goes into the storage.

Ideally, we'd want it to do:

• When on, sets a label on the storage.
• When off and storage has a label, remove the label.
• When off an storage does not have a label, goes into the storage.
