Describe the bug

The Docker Compose file correctly exposes port 4319, but the mounted Alloy configuration is misconfigured to use 4317 for the gRPC endpoint. This mismatch causes connection failures when attempting to access the service.

To Reproduce
Steps to reproduce the behavior:

1. Start Tempo
2. Attempt to connect via gRPC on port 4319
3. Observe that the connection fails

Expected behavior

• Alloy gRPC endpoint should listen on port 4319 instead of 4317, allowing clients to connect properly.

Environment:

• Infrastructure: [e.g., Kubernetes, bare-metal, laptop]
• Deployment tool: [e.g., helm, jsonnet]
