feat: update Jenkinsfile for improved CI/CD process

- Renamed stages for clarity, changing 'Checkout' to 'Git Clone from Gitea' and 'Build Image' to 'Build Docker Image'.
- Updated Git checkout step to use specific branch and credentials for Gitea.
- Enhanced Docker login process with `withCredentials` for better security.
- Added a new stage for deploying to production LXC, including SSH commands for directory creation and Docker management.
- Updated success and failure messages to include Korean language support for better localization.
