SettingNumberInput crashes in game

### My mods and Everest install are up to date

Yes

### I have recreated the bug with only Everest OR a minimum number of mods enabled

Yes

### Describe the bug

Trying to change a setting with `SettingNumberInput` while in game crashes.

### Steps to reproduce

1. Create a mod with a `SettingNumberInput` setting. The arguments don't matter.
2. Enter a level. It doesn't crash in the overworld.
3. Select the setting.

### Expected behavior

Given that the number input is an Oui element like the string input, I think the setting just shouldn't show up in game, like with strings. However, reworking the number and string inputs to work in game is the more correct fix, in my opinion.

### Operating System

Linux

### Everest Version

4896

### Mods required to reproduce

Any mod that uses `SettingNumberInput`, which may be none of them? IDK how this hasn't been noticed before.
