fix: run product sync in background batches to avoid 502 on large catalogs

Browse Source 
Manual and scheduled sync previously processed every WooCommerce product
inline in a single PHP request/AJAX call, with several sequential BC API
calls per product. At real catalog sizes this exceeds PHP's
max_execution_time and the proxy's read timeout, surfacing as a 502 Bad
Gateway on "Sync Now".

Adds WBC_Batch_Sync, which queues the catalog in chunks of 25 via Action
Scheduler (bundled with WooCommerce) and processes them asynchronously.
The manual sync AJAX call now returns immediately after queuing, and the
admin UI polls for progress instead of waiting on one long request.
