fix: Login logo 401, link focus styles, payment/shipping active colors

## 1. Fix Logo 401 Error on Login ✅

**Issue:** Logo image returns 401 Unauthorized on login page

**Root Cause:** `/store/settings` endpoint requires authentication

**Solution:** Created public branding endpoint
```php
// GET /woonoow/v1/store/branding (PUBLIC)
public function get_branding() {
    return [
        'store_name' => get_option('blogname'),
        'store_logo' => get_option('woonoow_store_logo'),
        'store_icon' => get_option('woonoow_store_icon'),
        'store_tagline' => get_option('woonoow_store_tagline'),
    ];
}
```

**Frontend:** Updated Login.tsx to use `/store/branding` instead

**Result:** Logo loads without authentication ✅

---

## 2. Override WordPress Link Focus Styles ✅

**Issue:** WordPress common.css applies focus/active styles to links

**Solution:** Added CSS override
```css
a:focus,
a:active {
  outline: none !important;
  box-shadow: none !important;
}
```

**Result:** Clean focus states, no WordPress interference

---

## 3. Active Color for Manual Payment Methods ✅

**Issue:** Manual payments use static gray icon, online payments use green/primary

**Solution:** Applied same active color logic
```tsx
<div className={`p-2 rounded-lg ${
  gateway.enabled
    ? 'bg-green-500/20 text-green-500'
    : 'bg-primary/10 text-primary'
}`}>
  <Banknote className="h-5 w-5" />
</div>
```

**Result:**
- ✅ Enabled = Green background + green icon
- ✅ Disabled = Primary background + primary icon
- ✅ Consistent with online payments

---

## 4. Active Color for Shipping Icons ✅

**Issue:** Shipping icons always gray, no visual indicator of enabled state

**Solution:** Applied active color to all shipping icons
- Zone summary view
- Desktop accordion view
- Mobile accordion view

```tsx
<div className={`p-2 rounded-lg ${
  rate.enabled
    ? 'bg-green-500/20 text-green-500'
    : 'bg-primary/10 text-primary'
}`}>
  <Truck className="h-4 w-4" />
</div>
```

**Result:**
- ✅ Enabled shipping = Green icon
- ✅ Disabled shipping = Primary icon
- ✅ Consistent visual language across payments & shipping

---

## 5. Notification Strategy ✅

**Acknowledged:** Clean structure, ready for implementation

---

## Summary

✅ Public branding endpoint (no auth required)
✅ Logo loads on login page
✅ WordPress link focus styles overridden
✅ Manual payments have active colors
✅ Shipping methods have active colors
✅ Consistent visual language (green = active, primary = inactive)

**Visual Consistency Achieved:**
- Payments (manual & online) ✓
- Shipping methods ✓
