Direct debit spotlight create authorization component crashes

**Describe the bug**

When I click 'create authorization' within the withdraw permission spotlight page it crashes.

**To Reproduce**

Go to the direct debit page: https://bts.exchange/#/direct-debit

Click 'create authorization' button 2 times.

**Expected behavior**

Dialog launches without problem.

**Additional context**

Errors:

ReferenceError: assignment to undeclared variable balance_fee

BindToChainState(t) ReferenceError: assignment to undeclared variable balance_fee

Also ocurring in the light client.

looking on kibana seems the last direct debit create operation 25 was june 5th 2023 so it's likely been broken for almost 2 years now.

Start by reproducing the crash from the Direct Debit page at https://bts.exchange/#/direct-debit, using the “create authorization” button twice. Trace the operation that raises the `balance_fee` ReferenceError, including the light client path; done means the authorization dialog launches reliably in both contexts.
