fix(front): fix setting default agent type, image in wf editor (#191)

## 📝 Description

**Fixes** #187

This PR introduces the following improvements:
- Sets the default machine type to the first available self-hosted agent
type.
- Sets the default container image for promotions that use Docker
environments.

### Behavior

- **Self-hosted agent default:**  
When adding a promotion with a block (without overriding global agent
definition), the first available self-hosted agent is selected by
default.

- **Docker environment default:**  
When adding a promotion with a block that uses a Docker environment, the
default container image is automatically set.
