What does this PR do?
Adds the Microservices Log Deployments and Changes pattern with centralized event history, automatic deployment and change outcome logging, a console timeline, and configurable alert filtering.
Includes documentation, a class diagram, and a manual CI workflow demonstrating simulated deployments and changes. Follows the existing log-aggregation module structure.
Validated with Java 21: all 5 tests pass, and Spotless formatting checks pass.
Fixes #2696
