Ensure all files end with a newline character

[Copilot]

14 files were missing final newline characters, which violates standard file format conventions and causes "no newline at end of file" warnings in tools like Git and linters.

Changes

• Added final newlines to 14 files across the repository:
  • POM files (5): root pom.xml, parent, core, actuator, and dependencies modules
  • Properties files (4): core, test, and actuator configuration
  • YAML files (1): test configuration
  • Markdown files (2): CODE_OF_CONDUCT.md, release-notes.md
  • GitHub config (2): dependabot.yml, maven-build.yml

Before/After Example

- </project>
\ No newline at end of file
+ </project>

All 138 source files in the repository now have proper final newlines.
