chore(workflows): update deployment configurations

- Modified the build-push workflow to trigger on all branches under "deploy/**" for broader deployment coverage.
- Changed the SSH host secret in the deploy-dev workflow from RAG_SSH_HOST to DEV_SSH_HOST for improved clarity.
- Removed the obsolete deploy-rag-dev workflow to streamline the CI/CD process.
