feat(FN-1874): add command/AI prompt type toggle to schedule form simple mode

- Add type toggle buttons (Command/AI Prompt) in simple schedule mode
- Show command input or AI prompt textarea based on selected type
- Add model provider/model ID fields for AI Prompt mode
- Restore simple type when editing existing schedules with single step
- Add comprehensive tests for type toggle behavior and validation
- Fix missing mocks in ScheduledTasksModal test
