fix: Admin SPA loading and remove MailQueue debug logs

Problem 1: Admin SPA not loading in production
Root Cause: Vite builds require type='module' attribute on script tags
Solution: Added script_loader_tag filter to add type='module' to admin SPA script

Problem 2: Annoying MailQueue debug logs in console
Solution: Removed all error_log statements from MailQueue class
- Removed init() debug log
- Removed enqueue() debug log
- Removed all sendNow() debug logs (was 10+ lines)
- Kept only essential one-line log after successful send

Changes:
- includes/Admin/Assets.php: Add type='module' to wnw-admin script
- includes/Core/Mail/MailQueue.php: Remove debug logging noise

Result:
✅ Admin SPA now loads with proper ES module support
✅ MailQueue logs removed from console
✅ Email functionality still works (kept minimal logging)

Note: Production zip is 21M (includes .vite manifests and dynamic imports)
