fix(ui): stuck viewer when spamming toggle

There are a number of bugs with `framer-motion` that can result in sync issues with AnimatePresence and the conditionally rendered component.

You can see this if you rapidly click an accordion, occasionally it gets out of sync and is closed when it should be open.

This is a bigger problem with the viewer where the user may hold down the `z` key. It's trivial to get it to lock up.

For now, just remove the animation entirely.
