This change introduces environment variable interpolation for volume paths, allowing users to customize where configuration, authentication, and log data are stored.
Why: Makes the project easier to deploy on various hosting environments that require decoupled data management without needing to modify the core docker-compose.yml..
Key points:
Defaults to existing paths (./config.yaml, ./auths, ./logs) to ensure zero breaking changes for current users.
Follows the existing naming convention used in the project.
Enhances portability for CI/CD and cloud-native deployments.
