Stracktrace in_app directives sent properly but ignored in Sentry

### Environment

self-hosted (https://develop.sentry.dev/self-hosted/)

### Steps to Reproduce

1. Sentry 25.9.0 / Laravel-Sentry 4.22.0
2. Configure in_app_include, e.g:
```php
'in_app_include' => [base_path('vendor/custom_one'),],
```
4. Trigger any exception
5. Check sentry json before send:
```json
# exception > values > stacktrace > frames > [{
"filename": "\/vendor\/custom_one\/File.php",
"lineno": 35,
"in_app": true,
"abs_path": "\/var\/www\/vendor\/custom_one/File.php",
```

Doesn't seem to be an SDK issue since "in_app" are sent

### Expected Result

All frames starting with "/vendor/custom_one" are shown by default and have an extra "In App" label

### Actual Result

Frames starting with "/vendor/custom_one" are hid by default, no "In App" label next to it

### Product Area

Issues

### Link

_No response_

### DSN

_No response_

### Version

25.9.0

Reproduce the behavior with Sentry 25.9.0 and Laravel-Sentry 4.22.0 using the shown in_app_include configuration. Compare the submitted stacktrace frames with how the Issues product displays frames, focusing on the in_app field, hidden frames, and the missing In App label. Done means matching frames are shown by default with the label.
