refactor: standardize Bruno API requests with bruToJsonV2 format

- Convert all JSON tests to JavaScript functions for bruToJsonV2 compatibility
- Update authentication to use 'inherit' instead of manual headers
- Fix hardcoded URLs to use {{base_url}} variables
- Standardize variable syntax from {{ _.var }} to {{var}}
- Add comprehensive API documentation to all requests
- Update environment variables with missing required fields
- Apply consistent structure: meta, http method, headers, tests, vars, settings, docs
- Enhanced validation with proper error handling and field checks
