fix: Track order completion BEFORE clearing checkout

The checkout was being cleared before tracking, causing getTotal()
to return 0. Fixed by reordering operations:
1. Track order completion (while checkout data exists)
2. Then clear the checkout

Added console log to verify total is captured correctly.
