build: Add comprehensive clean targets and legacy cleanup

Improves build hygiene by ensuring all generated artifacts are removed
during clean operations.

Changes:
* Global Clean: Added a top-level `clean-all` target in
  `mirth-build.xml` that cascades to all sub-projects.
* Legacy Cleanup: Introduced `clean-legacy-dirs` target to remove
  obsolete directories (`junit-reports`, `code-coverage-reports`)
  ensuring developers do not view stale reports.
* Deep Clean: Updated sub-project clean targets to include
  `${test_classes}` and `${build.dir}`, preventing stale class files
  from polluting subsequent builds.
