Wires up Helcim's free WooCommerce plugin (installed inert until a sandbox
token exists) alongside a synchronous pre-charge supplier/margin recheck
and a fraud-check hook, both firing immediately before payment per the
Appendix B immediate-charge decision. Adds a custom order-status sequence
(bsc-ordered/bsc-shipped/bsc-exception) as the state machine and review
queue, an Action Scheduler-backed supplier-submission job with idempotency
guards, a bsc_order_audit ledger, and two new transactional emails.
Hooks both the classic WooCommerce checkout actions and the real
woocommerce_checkout_validate_order_before_payment hook, since this site's
storefront runs WooCommerce Blocks/Store API rather than the classic
shortcode checkout (confirmed by reading WooCommerce's own source after
the classic hooks turned out not to fire in live testing).
