fix: use WC attribute ID (not name) when setting variation attributes

WooCommerce silently ignores attribute 'name' on variation updates —
requires 'id' (the WC attribute ID). Built a lookup map from the
parent product's wc_attributes and use 'id' in all variation payloads.
Fixed in all 3 files: variant push wizard, product creation wizard,
and product map direct push.
