unable to save changes to category builder

[xenonfire54]

• I am on the latest ActivityWatch version.
• I have searched the issues of this repo and believe that this is not a duplicate.

• EndeavourOS x86_64 Kernel: Linux 6.18.7-arch1-1, as well as Windows 11 latest version 10.0.26200.7705:
• ActivityWatch version v0.13.2:

Describe the bug

To Reproduce

Steps to reproduce the behavior:
1. Go to activitywatch settings page on web view
2. Click on any category, or add a new category to edit it
3. try editing the category information
4. succeed
5. see a glaring lack of a save button
6. See error

Expected behavior

I expected to be able to save the changes to the category builder, as in previous versions

Documentation

Additional context

category information can be changed and viewed correctly by exporting the categories, then changing the information manually, and importing the categories, but that is inconvenient for most users.
