fix: Enable email notifications by default with default templates

🐛 CRITICAL FIX - Root Cause Found:

Problem 1: Events Not Enabled by Default
- is_event_enabled() returned false if not configured
- Required explicit admin configuration
- Plugin didn't work out-of-the-box

Solution:
- Enable email notifications by default if not configured
- Allow plugin to work with default templates
- Users can still disable via admin if needed

Problem 2: Default Templates Not Loading
- EmailRenderer called get_template() with only 2 args
- Missing $recipient_type parameter
- Default template lookup failed

Solution:
- Pass recipient_type to get_template()
- Proper default template lookup
- Added debug logging for template resolution

📝 Changes:

1. EmailManager::is_event_enabled()
   - Returns true by default for email channel
   - Logs when using default (not configured)
   - Respects explicit disable if configured

2. EmailRenderer::get_template_settings()
   - Pass recipient_type to TemplateProvider
   - Log template found/not found
   - Proper default template resolution

🎯 Result:
- Plugin works out-of-the-box
- Default templates used if not customized
- Email notifications sent without configuration
- Users can still customize in admin

✅ Expected Behavior:
1. Install plugin
2. Create order
3. Email sent automatically (default template)
4. Customize templates in admin (optional)

This fixes the issue where check-settings.php showed:
- Email: ✗ NOT CONFIGURED
- Templates: 0

Now it will use defaults and send emails!
