Streamlined Keycloak configurations with defaults for development and production in `.env`. Added health checks and improved environment variable documentation with comments to differentiate local and server deployments. Ensured compatibility with pre-built registry images.
Added a detailed guide on enabling caching for Gitea Actions to accelerate CI/CD workflows in `docs/01_Architecture/Gitea/Enable_Gitea_Actions_Cache_to_Accelerate_CI_CD.md`. Updated `.gitignore` to exclude the `/_backup/` directory.
