Background

PR #1148 successfully removed the YAML configuration dependency for database credentials from several CLP components and replaced it with environment variables and CLI arguments. However, the GLT component was not modified in this PR and still retains the yaml-cpp dependency.

Task

Propagate the changes from PR #1148 to the GLT component to:

• Remove yaml-cpp dependency from GLT
• Replace YAML config with environment variables and CLI arguments for database configuration
• Ensure consistency across all CLP components

Acceptance Criteria

• Database configuration in GLT uses environment variables and CLI arguments
• All yaml-cpp references are removed from the entire codebase
• Documentation is updated if needed
