fix: resolve live monitoring bug, remove deprecated parameters, and auto-start Python worker

- Fix live monitoring style error by calling _live_monitor() helper directly
- Remove default_parameters duplication from 10 workflow metadata files
- Remove deprecated volume_mode parameter from 26 files across CLI, SDK, backend, and docs
- Configure Python worker to start automatically with docker compose up
- Clean up constants, validation, completion, and example files

Fixes #
- Live monitoring now works correctly with --live flag
- Workflow metadata follows JSON Schema standard
- Cleaner codebase without deprecated volume_mode
- Python worker (most commonly used) starts by default
