Make a Lit component that handles displaying items (with auto-collapse, etc)

[dukio]

Currently we are displaying items in multiple parts of the website:

• Active Armor
• Weapons
• Accessories
• Pets
• Mining Tools
• Farming Tools
• Fishing Rods

I feel like all these sections could use a main component that automatically handles hiding items after a certain number has been displayed... we are already doing it for pets, but not for the rest, and the result is this (see hoes): https://sky.shiiyu.moe/stats/Bankhier/Papaya#Skills

This should probably share code with the rich item element from the inventory
