Issue:
[Bug]: Input type of `hide_globally` during API modification of categories is incorrect
### Bug Summary

The API returns an error when changing the `hide_globally` field of a category using correct input

### Description

This interaction fails:

```
curl -Ssu 'REDACTED' 'http://localhost:8080/v1/categories/4' -X PUT --json '{"hide_globally":true}'  | jq
{
  "error_message": "json: cannot unmarshal bool into Go struct field CategoryRequest.hide_globally of type string"
}
```

It would appear the input type is incorrectly defined, as it clearly should be a boolean rather than a string. Similarly modifying a feed works as expected.

### Steps to Reproduce

See description

### Expected Behavior

The category should be modified without error.

### Actual Behavior

An error about type conversion is returned.

### Version

2.2.7

### Browser

Curl

### Relevant Logs or Error Output

```shell

```

### Additional Context

_No response_

### Checklist

- [x] I have searched existing issues to ensure this bug hasn't been reported before.
