The field rendered in two places on /user/revenue/: the 我的佣金 card's
meta line and the 累计佣金 row, both gated on a non-zero balance. Remove
both, along with the now-unused $debt_amount local and the dead
.uc-commission-card__debt rule.
Source trace, since the label is only the surface: CommissionLedger::
overview() reads debt_minor from aksrt_commission_debt and returns it as
'debt'; record_debt() books the shortfall when a refund cannot be clawed
back in full, and repay_debt_from_pool() later clears it out of the
commission pool. That mechanism is untouched — arrears still accrue and
still get repaid, the UI just no longer surfaces them. The reference
theme's rebate card has no equivalent concept, so this is not a parity
target either.
Keep 'debt' in the template's overview() fallback array: it mirrors the
real return shape and the repayment path still depends on the value.
Add a contract test asserting the label, its class and the local are gone
from the display layer while overview() keeps returning the key; verified
it fails if the label is reintroduced.
