Inventory is loaded at app start

[lalalune]

Describe the bug Right now, the application is loaded every app, screenshotting previews, all kinds of stuff, even for temp apps, inventory items, etc. This should really be lazy loaded. Chances are that there are 'display: none' things that are affecting our performance, considering those components are loading on start at all.

To Reproduce Steps to reproduce the behavior: Start app Check logs Why are we loading the dragon and sword which are only in our inventory? We've never opened our inventory. Why is this loading right away?

Expected behavior A azy loading strategy for inventory and other dynamic UI the first time

We need to make sure that the UI isn't rendering or loading needlessly across the board. There are some things done with css manipulation that can be approached with functions instead. The whole frontend needs to be cleaned up.
