updates and refactoring

[ncode]

• This pull request includes several significant changes to the project, focusing on refactoring, configuration updates, and error handling improvements. Key changes include updating context imports, enhancing error handling, and renaming and restructuring configuration files.

Refactoring and Error Handling:

• cmd/run.go: Replaced the deprecated golang.org/x/net/context with the standard library context package. Added an os.Exit(1) call to handle errors more gracefully.
• internal/ballot/ballot.go: Refactored the Command method to CommandContext to support context cancellation. Improved error handling and added validation checks for required fields in the Ballot

Configuration Updates:

• configs/consul_with_3_nodes/: Removed old JSON configuration files for Consul agents and replaced them with new HCL configuration files.
• configs/development/: Renamed and updated Dockerfile and Makefile to reflect the new development environment structure.
• configs/development/docker-compose.yaml: Updated the Docker Compose file to enable script checks and client settings for Consul agents. Removed the custom network configuration.

Consistency Improvements:

• configs/development/ballot-1/ballot.yaml, configs/development/ballot-2/ballot.yaml, configs/development/ballot-3/ballot.yaml: Standardized service IDs and names to use hyphens instead of underscores.

These changes enhance the project's maintainability, error handling, and configuration consistency.
