test: Fix privacy template test expectations and add coverage for auto-cleanup

## Test Improvements

### Template Coverage Updates
- **Added privacy-auto-cleanup.sh.j2** to active test templates (was commented out)
- **Updated test variables** to include missing `clean_package_cache` parameter
- **Added validation logic** for auto-cleanup template rendering

### Pattern Matching Fixes
- **Fixed regex expectations** to match actual strengthened patterns:
  - Changed `CHILD_SA.*established` to `CHILD_SA [^[]+ established`
  - Updated both positive and negative test cases consistently
- **Enhanced template validation** with specific assertions for auto-cleanup script

### Test Variables Enhancement
- **Complete privacy_auto_cleanup config**: Added `clean_package_cache: True`
- **Comprehensive test coverage**: All privacy templates now properly tested
- **Robust validation**: Template-specific content assertions for each template type

## Verification Results
- ✅ **4/4 privacy tests passing**
- ✅ **Template rendering validation** for all existing templates
- ✅ **Proper error handling** for missing templates (99-privacy-enhanced.j2)
- ✅ **Regex pattern security** validation working correctly

This addresses the feedback about template file gaps - the auto-cleanup template exists and is now properly tested, with only the intentionally unimplemented 99-privacy-enhanced.j2 remaining commented out.
