Add comprehensive test coverage for restore plugins

- Add test files for all restore.go files that were missing tests
- Update existing test files to improve coverage:
  - horizontalpodautoscaler: Add Execute() tests for all scenarios
  - pod: Add tests for AppliesTo(), PodHasVolumesToBackUp(), and PodHasRestoreHookAnnotations()
  - route: Add Execute() tests for route host generation scenarios
- Add documentation comments explaining where Execute() functionality is tested for plugins that only test AppliesTo()
- Fix failing tests by adjusting to match implementation behavior
