debug: Log ALL REST API requests to see actual routes being called

Added rest_pre_dispatch filter to log EVERY REST API request.

This will show us:
- What route is actually being called
- If it's /woonoow/v1/products or something else
- If WordPress is routing to a different endpoint

Expected log: WooNooW REST: GET /woonoow/v1/products
If we see different route, that's the problem!
