BankCreditLimitAdjuster class

User-controlled credit limit card: the customer drags their own limit.

Shows the currently selected limit as a large numeral that updates live while dragging, above a slider spanning from the amount already used (the limit can never drop below current usage) up to the bank approved maximum. Values snap to round increments and a subtle marker on the track pins the limit configured today. A thin used-versus-limit progress bar turns BankTokens.danger once utilisation passes 90 percent of the selection.

A commit button appears only when the selection differs from the configured limit: it shows an inline spinner while onCommit runs, flashes a success check when it resolves true, and reverts the slider to the configured limit when it resolves false or throws.

Money is rendered through BankBalanceText and BankMoneyFormatter, so privacy mode and numeral style from the ambient BankUiScope are respected. The slider announces formatted values to assistive technologies.
