fix(hermes-web-cli): correct new_session.ui implementation

- Change service_id field uitype from 'select' to 'code' (bricks has no select type)
- Create hermes_services/list/index.dspy endpoint to provide service list data for code component
- Use Form's built-in submit/cancel buttons instead of manual Button widgets
- Add sessions.json CRUD definition for session management
- Ensure proper data format for code component: {"value": "id", "text": "name"}
