refactor(build): remove docker-compose hardcoded file, update compose dependencies, and resolve library conflicts

Deleted the unused `compose.hardcoded.yaml` file. Updated Gradle build scripts to resolve issues with Jackson and Resilience4j library bundles by explicitly specifying direct dependencies. Removed the `sqldelight` plugin and related dependencies from `local-db` module. Consolidated `docker-compose.yaml` to standardize restart policies. Adjusted `.env` to include cautions for sensitive data and rechecked Java version comments.
