Fix OCMOD targeting wrong template file (product.twig vs product_form.twig)

OC3 on this host uses product_form.twig, not product.twig. OC3 silently
skips OCMOD operations for files that don't exist, explaining why the tab
never appeared and the modification log showed no errors.

Also wrap getSyncEnabledProducts() in try/catch so sync failures return a
descriptive JSON error instead of a raw PHP exception causing a 500.
