This commit adds the ability to use cloud-init scripts when creating Hetzner servers through the integration. Users can write custom scripts that will be executed during server initialization, and optionally save these scripts at the team level for future reuse.
Key features:
- Textarea field for entering cloud-init scripts (bash or cloud-config YAML)
- Checkbox to save scripts for later use at team level
- Dropdown to load previously saved scripts
- Scripts are encrypted in the database
- Full validation and authorization checks
- Comprehensive unit and feature tests
