feat: multi-select AI types in configurator

- Changed aiType (string|null) to aiTypes (string[]) across all components
- StepServices: chips now toggle on/off independently, descriptions show for all selected
- StepContact: summary tags show all selected AI types
- API route: handles array of AI types for both AI and fallback brief generation
