fix: Complete UI/UX polish - all 7 issues resolved

## ✅ Issue 1: Customers Submenu Missing in WP-Admin
**Problem:** Tax and Customer submenus only visible in standalone mode
**Root Cause:** PHP navigation registry did not include Customers
**Fixed:** Added Customers to NavigationRegistry.php settings children
**Result:** Customers submenu now shows in all modes

## ✅ Issue 2: App Logo/Title in Topbar
**Problem:** Should show logo → store name → "WooNooW" fallback
**Fixed:** Header component now:
- Fetches branding from /store/branding endpoint
- Shows logo image if available
- Falls back to store name text
- Updates on store settings change event
**Result:** Proper branding hierarchy in app header

## ✅ Issue 3: Zone Card Header Density on Mobile
**Problem:** "Indonesia Addons" row with 3 icons too cramped on mobile
**Fixed:** Shipping.tsx zone card header:
- Reduced gap from gap-3 to gap-2/gap-1 on mobile
- Smaller font size on mobile (text-sm md:text-lg)
- Added min-w-0 for proper text truncation
- flex-shrink-0 on icon buttons
**Result:** Better mobile spacing and readability

## ✅ Issue 4: Go to WP Admin Button
**Problem:** Should show in standalone mode, not wp-admin
**Fixed:** More page now shows "Go to WP Admin" button:
- Only in standalone mode
- Before Logout button
- Links to /wp-admin
**Result:** Easy access to WP Admin from standalone mode

## ✅ Issue 5: Customer Settings 403 Error
**Problem:** Permission check failing for customer-settings endpoint
**Fixed:** StoreController.php check_permission():
- Added fallback: manage_woocommerce OR manage_options
- Ensures administrators always have access
**Result:** Customer Settings page loads successfully

## ✅ Issue 6: Dark Mode Logo Upload Field
**Problem:** No UI to upload dark mode logo
**Fixed:** Store settings page now has:
- "Store logo (Light mode)" field
- "Store logo (Dark mode)" field (optional)
- Backend support in StoreSettingsProvider
- Full save/load functionality
**Result:** Users can upload separate logos for light/dark modes

## ✅ Issue 7: Login Card Background Too Dark
**Problem:** Login card same color as background in dark mode
**Fixed:** Login.tsx card styling:
- Changed from dark:bg-gray-800 (solid)
- To dark:bg-gray-900/50 (semi-transparent)
- Added backdrop-blur-xl for glass effect
- Added border for definition
**Result:** Login card visually distinct with modern glass effect
