fix: resolve template content syntax errors in 4 advanced templates

- Fix template-transform nodes using invalid 'template_content' syntax
- Replace with correct 'template' structure with 'type', 'source', 'content'
- Add proper 'template_parameters' for variable substitution
- Add 'output_variable' to all template-transform nodes
- Remove invalid node references like {{node_id.output}}
- Use  syntax for environment variables
- All 4 templates now validate and compile successfully

Resolves: 'Failed to resolve template content' errors in:
- multi-stage-ai-workflows-template.yaml
- multi-format-distribution-template.yaml
- parallel-processing-aggregation-template.yaml
- automated-testing-monitoring-template.yaml
