[Bug]: Split transactions amounts cannot be input in mobile

### Verified issue does not already exist?

### What happened?

Can't input amounts on split transactions on mobile.
Basically, I can input transactions no problem, but when I try to do a split transaction from mobile (iOS latest), the split fields are created but I can't input numbers, is like they reset to 0 no matter what I input, therefore, I can't save the transaction since the split is invalid. I have tried in Safari, Chrome, and DuckDuckGo, neither works. Desktop client version works no problem, desktop browser version works as well.

Also, just realized as I write this that splits work as intended in my USD budget file, it is just the JPY that misbehaves.

### How can we reproduce the issue?

How can we reproduce the issue?

I have no idea, it just happens from the beginning. I used to host locally and it happened. Now I am hosting on Google Cloud, it still happens.

### Where are you hosting Actual?

Docker

### What browsers are you seeing the problem on?

Safari

### Operating System

Mobile Device

No files, tests, or code entry points are identified in the issue. Reproduce the split-transaction flow on an iOS device using a JPY budget, comparing Safari with the working desktop and USD cases. Done means split amounts remain editable and persist so the transaction can be saved successfully.
