Fix cyclic object error in onboarding step completion

**Issue:**
When clicking Continue button in setup steps (quality, inventory, recipes,
team, review), got error: "cyclic object value"

**Root Cause:**
Button onClick handlers were passing React event object directly to onComplete:
```tsx
onClick={onComplete}  // Passes event as first argument
```

React event objects have circular references (target, currentTarget, etc.)
which cannot be JSON.stringify'd for API calls.

**Solution:**
Wrap all onComplete calls in arrow functions to prevent event from being passed:
```tsx
onClick={() => onComplete()}  // Calls with no arguments
```

**Files Fixed:**
- QualitySetupStep.tsx:436
- InventorySetupStep.tsx:1014
- RecipesSetupStep.tsx:801
- ReviewSetupStep.tsx:314
- TeamSetupStep.tsx:318

**Error Log (Before Fix):**
```
Completing step: "quality-setup" with data:
Object { _reactName: "onClick", _targetInst: null, type: "click", ...
❌ API error: "cyclic object value"
```

**After Fix:**
✅ onComplete() called with no arguments
✅ No event object passed to API
✅ Step completion works correctly
