fix(accounting): post GL entries for a negative (clawback) interest transaction

A premature FD closure that reprices interest downward (e.g. a pre-closure
penalty) posts the difference as a negative interest-posting transaction --
a clawback of interest already recognised in earlier periods. Both the cash-
and accrual-based accounting processors only posted journal entries when the
transaction amount was greater than zero, so a clawback updated the FD
subledger but silently posted nothing to the General Ledger, leaving the two
out of sync.

Treats a negative amount as a mirror-image reversal: positive magnitude,
debit/credit legs swapped -- the same mechanism already used for isReversal.
