fix: Properly update gateway enabled property + add debug logging

🔍 Suspect #7: Gateway enabled property not being updated

Problem:
- We save to database ✅
- We reload settings ✅
- But $gateway->enabled property might not update!

Root Cause:
WooCommerce has TWO places for enabled status:
1. $gateway->settings['enabled'] (in database)
2. $gateway->enabled (instance property)

We were only updating #1, not #2!

The Fix:
// Update both places
$gateway->settings = $new_settings;  // Database
update_option($gateway->get_option_key(), $gateway->settings);

if (isset($new_settings['enabled'])) {
    $gateway->enabled = $new_settings['enabled'];  // Instance property!
}

Added Debug Logging:
- Log toggle request (gateway ID + enabled value)
- Log save process (current vs new enabled)
- Log update_option result
- Log final enabled value after fetch
- All logs prefixed with [WooNooW] for easy filtering

How to Debug:
1. Toggle a gateway
2. Check debug.log or error_log
3. Look for [WooNooW] lines
4. See exact values at each step

Files Modified:
- PaymentGatewaysProvider.php: Update both settings + enabled property
- PaymentsController.php: Add debug logging

Next Step:
Test toggle and check logs to see what's actually happening!
