Add an item for labelling/organization in stashes

Add an item to help with organization and labeling within stashes.

Instead of the notes/notepad it could be a sticky note. You can write on it like a notepad, but when you hover over the item in the stash/inventory it shows whatever you wrote on the sticky note. You could enforce a word/character limit too so it’s realistic to a sticky note and can only really be used for labels or quick notes.

I think this would be a good QoL item that could make organizing within stashes so much easier.
