feat(server): enhance workflow step execution and JSONata integration

- Refactored step execution logic to introduce runCompiledStep for improved clarity and functionality.
- Added support for "set" steps, allowing context manipulation using JSONata expressions.
- Implemented evaluateJsonata and isJsonataTruthy functions for evaluating conditions and expressions.
- Updated workflow parsing to handle new step types and validation rules.
- Enhanced logging and error handling for skipped steps and invalid configurations.
- Modified UI components to reflect new step types and statuses, including "skipped".
