Local File Serving Not Working in Docker Container Despite Correct Environment Variables

**Describe the bug**
I'm running Label Studio inside a Docker container using docker-compose. I've set up environment variables to access data from local files (linked to a volume). The files exist when checking within the container, but I cannot access them through URLs from the browser or within the container.

**To Reproduce**
Steps to reproduce the behavior:
1. Create a docker-compose.yml with the following Label Studio service configuration:

```yaml
labelstudio:
image: heartexlabs/label-studio:latest
ports:
- "4999:8000"
depends_on:
- database
environment:
- LABEL_STUDIO_LOCAL_FILES_SERVING_ENABLED=true
- LABEL_STUDIO_LOCAL_FILES_DOCUMENT_ROOT=/label-studio/data
- LABEL_STUDIO_BASE_DATA_DIR=/label-studio/data/
- LABEL_STUDIO_CORS_ORIGIN=*
- LOG_LEVEL=DEBUG
volumes:
- label_studio_mydata:/label-studio/data:rw
- documents_dataset:/label-studio/data/raw_datasets/documents_dataset:rw
command: label-studio-uwsgi
```

1. Start the Label Studio container.

2. Inside the container, create a test file:

echo "this is fake image" > /label-studio/data/raw_datasets/documents_dataset/document1/document1_Page_01.jpg
2.Attempt to access the file via browser:
http://localhost:4999/data/local-files/?d=raw_datasets/documents_dataset/document1/document1_Page_01.jpg
2.Attempt to access the file from within the container:
Copy curl -v 'http://localhost:8000/data/local-files/?d=raw_datasets/documents_dataset/document1/document1_Page_01.jpg'

**Expected behavior**
The file should be accessible via the provided URLs.
Actual behavior

Browser access fails
Curl command from within the container fails to retrieve the file

**Environment information:**

Label Studio Version: Label Studio version: 1.12.1

**Additional context**

Environment variables are correctly set within the container:
LABEL_STUDIO_LOCAL_FILES_SERVING_ENABLED=true
LABEL_STUDIO_LOCAL_FILES_DOCUMENT_ROOT=/label-studio/data
LABEL_STUDIO_BASE_DATA_DIR=/label-studio/data/

The files are present and accessible within the container when checked directly.
Unable to find Label Studio configuration file (/label-studio/data/label_studio_config.json) within the container.
Unable to locate or access Label Studio log files within the container.

**Attempted troubleshooting:**

Verified file permissions within the container
Checked environment variables
Attempted to access a simple text file using curl within the container (failed)

Any assistance in resolving this issue would be greatly appreciated.
